A Look Beyond Massive MIMO – Working with a Huge Number of Antennas Future wireless systems are expected to provide huge growth in user bit rates and overall required bit rates, and the same might be expect for beyond 5G systems. This means a substantial spectral efficiency increase, which must be achieved while maintaining or even improving the power efficiency. To accomplish this one needs to employ new transmission techniques, with the most promising ones based on the use of a large number of antennas. For this reason, massive MIMO (Multiple-Input and Multiple-Output) schemes, involving tens or even hundreds of antennas, are a key component of 5G, since they allow high capacity gains, while enabling significant power savings. Clearly, the evolution beyond 5G will involve even more antennas. A new and revolutionary technique able to improve substantially the performance of wireless communication networks is to smartly changing the propagation characteristics of the wireless channel through the use of RIS (Reconfigurable Intelligent Surfaces), which are made of a large number of low cost passive reflecting elements able to independently change the amplitude and/or phase of the incident signal so as to achieve specific propagation effects. LIS (Large Intelligent Surfaces) are the natural evolution of massive MIMO schemes. They will employ many thousands of antenna elements, allowing huge capacity gains, as well accurate positioning and efficient energy harvesting techniques. However, the implementation of these techniques involves considerable challenges. In this talk we give an overview of potentialities and challenges of systems with a huge number of antennas. We start by making an overview on the evolution from MIMO to massive MIMO, and its extension to RIS and LIS and cell free systems. Then we present the main features of those systems, as well as the implementation constraints and challenges, as well as potential solutions.

Abstract: Nowadays, both digital and analog electronics are reaching fundamental limits that will require revolutionary approaches to satisfy the power/bandwidth requirements of the next generation of data-driven applications. In the first part of the talk, analog and digital signal processing will be compared in terms of power efficiency by highlighting the presence of a thermodynamic upper-bound which relates dynamic range, bandwidth and power dissipation. To circumvent this limit, in the second part of the talk, the quantized-analog signal processing will be introduced. In such approach, analog and digital domains are merged together in a more fluid scenario compared to traditional mixed-signal circuits avoiding the needs of rigid interfaces such as analog-to-digital and digital-to-analog converters. It will be shown that the quantized-analog signal processing leads to superior power efficiency and flexibility compared to its analog counterpart and it represents a good candidate for the development of a new generation of mixed signal integrated circuits. The effectiveness of the proposed solutions will be demonstrated through simulations and measurement results.

Join us for an insightful virtual webinar on "The Engineer’s Guide to AI Strategy: Bridging the Gap Between Business and Technical Reality" hosted by the IEEE Women in Engineering Oregon Section AG and co-hosted by Spokane Section, Seattle Section San Francisco section, Santa Clara Valley Section, and San Fernando Valley Section WIE AG where we challenge the traditional boundaries between strategy, governance, and engineering. The rapid rise of Artificial Intelligence has led to countless “Proof of Concepts” that never make it to production—and production systems that fail spectacularly when they do. Why does this happen? A key reason lies in how organizations traditionally separate Strategy and Governance from Engineering execution. Strategy is often treated as a conceptual exercise, while governance is reduced to compliance checklists—leaving engineers disconnected from the very decisions that shape successful AI systems. In this insightful session, we challenge that paradigm. We will explore how engineers must evolve from execution-focused contributors to strategic decision-makers, integrating governance and strategy as core technical requirements in AI system design. Participants will learn how to bridge the gap between business vision and engineering reality by embedding strategy, governance, and ethical considerations directly into the development lifecycle. Additionally, the session will highlight practical strategies for women in tech to strengthen their influence—through confident communication, strategic thinking, and authentic leadership. Key Learning Objectives - Understand why many AI systems fail to transition from concept to production - Learn how to align engineering decisions with organizational strategy - Explore how to embed governance and safety into AI pipelines - Develop a strategic engineering mindset - Gain practical insights on influencing effectively as a woman in technology Who Should Attend - Engineers and AI practitioners - Early-career professionals and students - Technical leaders and project managers - Anyone interested in AI strategy, governance, and leadership development Speaker(s): Kierra Dotson Agenda: - Welcome & Overview of IEEE WIE Oregon Section Affinity Group - Invited talk from Kierra Dotson - Q/A Session Virtual: https://events.vtools.ieee.org/m/553802

Title: Fractional-N Phase-Locked Loops Using Harmonic-Mixer-Based Feedback and Noise Cancellation Abstract: Frequency synthesizers are an integral part of various applications, such as wireless and wireline communication systems. The generation of frequency sources with low phase noise under limited power, area, and many other factors has been an ongoing challenge over the years. Especially for the fractional-N phase-locked loops (PLLs), the suppression of quantization noise (Q-noise) and spurs has been one of the main challenges. Architectures based on quantization error cancellation, either in the time domain using digital-to-time converters or in the voltage domain using digital-to-analog converters, have been popular in recent years. However, the circuits used for the cancellation are often affected by PVT-related gain errors and non-linearity, requiring intensive digital calibration to prevent severe performance degradation. In this talk, we introduce some harmonic-mixer-based fractional-N PLL architectures that avoid the amplification of the Q-noise by the loop. With this concept, we can effectively suppress the contribution of the Q-noise at the PLL output without applying intensive calibration.

Abstract: The next generation of wireless networks will no longer be confined to moving bits — they will sense, communicate, and learn simultaneously. This convergence is anticipated to enable distributed intelligence across devices, unlocking new capabilities for real-time perception and decision-making in dynamic environments. In this talk, two complementary advances in federated signal processing will be presented. First, an over-the-air federated edge learning (OTA-FEEL) framework with integrated radar sensing will be discussed. By leveraging echoes from the environment, rather than treating them solely as interference, robust model aggregation will be maintained while ensuring high-quality sensing and communication performance. A joint scheduling and beamforming design will be presented, supported by low-complexity optimization techniques, to preserve aggregation accuracy under realistic wireless conditions. Second, FedTrack, a novel federated learning–inspired algorithm for distributed target tracking, will be presented. By treating local log-likelihood functions as loss functions in a distributed optimization framework, FedTrack enables devices to collaboratively estimate a moving target’s position and velocity. This communication-efficient method closely approximates centralized maximum likelihood estimation, achieving accuracy near the Cramér–Rao bound while reducing reliance on a central coordinator. Together, these developments illustrate how federated intelligence over the air can transform 6G networks into systems that not only communicate but also sense and learn collaboratively. Implications for autonomous systems, smart cities, and beyond will be discussed, with emphasis on the central role of signal processing innovations in realizing this vision.

Future of communication and sensing network is being transformed with the advancement in next generations of wireless with Beyond-5G, beyond-WiFi-8, ICAS, NTN, VR/XR/Metaverse, Digital-Twin and other emerging applications. Higher quality of experiences for connected future with ubiquitous lowest latency and superhigh data rate connectivity services will require innovative wireless technologies and communication hardware combined with AI/ML. Mobile platform integrated RF systems with antenna front ends are common factor for most of the wireless applications. Emerging usage scenarios will need intelligent mobile platforms with ultra-small form-factor, requiring co-design and heterogeneous integration of dis-similar semiconductor device, circuit and antenna technologies, in order to satisfy the desired application-specific performance criteria for the evolving use cases. This presentation will present the emerging technology trends and will focus on the antenna-integrated RF to mm-wave/THz array integrated frontend opportunities and challenges demanding new technology, design, development and integration. Example architectures to enable multifunction microsystem platform will be discussed.

EXCOM Meeting for IEEE PES Seattle Officers Virtual: https://events.vtools.ieee.org/m/521448

IEEE WIE AG Schenectady is going to organize WIE Distinguished Lecture (virtual webinar) on "Human System Engineering Initiatives: From Human Views to Human Readiness Levels" on 5 June 2026, Friday, 12-1 pm EDT. The speaker is Holly A. H. Handley, PhD, PE, the Interim Dean of the Interdisciplinary Schools and a Professor in the Engineering Management and System Engineering Department of Old Dominion University (ODU). This talk discusses the role of Human System Engineering within the System Engineering discipline. It describes two initiatives that are enabling better integration of humans and systems. The Human Views comprise a system architecture viewpoint that provides a perspective on the human roles, activities, and information flows required by a complex system. The Human Readiness Levels assess the degree to which human-focused requirements are incorporated into design decisions and the readiness of a system to interact with its human operator. Together these two efforts encourage System Engineering for the total system by supporting a comprehensive integration of the human component into the systems engineering effort, which is critical to the design, development, and operation of successful systems. Current standards and applications of both initiatives will be included. Speaker(s): Holly Handley Virtual: https://events.vtools.ieee.org/m/550987
