The emergence of Non-terrestrial networks (NTN) has become a crucial driver for the next generation of wireless communication systems. NTN encompasses satellite and aerial segments, which can function either as relay nodes or base stations. In the upcoming years, NTN will play a crucial role in supporting universal connectivity where everyone and everything will need to be connected: from any geographic location and including every application from consumer broadband to mobile gaming. These requirements will lead to the development of advanced microwave systems that provide superior connectivity, while minimizing costs. This sector is expected to experience significant growth in the near future. Consequently, researchers worldwide are actively engaged in devising innovative technological solutions that can adapt to diverse scenarios, satisfy performance requirements, and conform to cost, size, and power consumption limitations. The impact of these efforts will be broad, encompassing research and development on antennas, RF integrated systems, integration and semiconductor technology, as well as system design. This presentation reports a multidisciplinary perspective on this topic, which includes a review of current solutions and an examination of emerging configurations from both architectural and technological <a href="http://viewpoints.Speaker(s):" target="_blank" title="viewpoints.Speaker(s):">viewpoints.Speaker(s): , LuigiBldg: Emera IDEA building, 1345 Norma Eddy Ln, Halifax, Nova Scotia, Canada, B3J 0H6, Virtual: https://events.vtools.ieee.org/m/551595

The kick-off event of the signature Lunch&Learn series of IEEE Young Professionals Ottawa will have Prof. Burak Kantarci, a highly distinguished expert on automated systems and communications, as well as surprises and treats including Turkish coffee!Title: Spectrum Intelligence for 6G and Uncrewed Systems (UxS): Security, Coexistence, and Edge AutonomyAbstract: Uncrewed systems (UxS) are moving from niche applications to large-scale deployments across logistics, infrastructure inspection, public safety, and defence-adjacent operations. What makes or breaks these deployments is not just the autonomy of the platform itself, but the reliability, security, and intelligence of its communications in a crowded and contested spectrum environment. This talk addresses exactly that problem. We show how machine learning is redefining the radio access layer for uncrewed systems operating in shared spectrum: detecting jamming and spoofing at the RF signal level, classifying interference from coexisting users, predicting spectrum occupancy, and enabling dynamic access decisions that protect command-and-control link integrity in real time. Drawing on recent work in deep ensemble learning and RF fingerprinting, we demonstrate how AI models trained on raw IQ and spectral data can expose threats and opportunities in the spectrum that are invisible to conventional signal processing. We then examine how fleets of uncrewed platforms can become active participants in spectrum coordination rather than passive spectrum consumers. Through federated learning and multi-agent reinforcement learning, uncrewed nodes collaboratively develop spectrum access policies adapted to their operational environment, without offloading sensitive mission data to centralized infrastructure. This is precisely the kind of distributed, scalable spectrum intelligence that next-generation shared-access frameworks, including those governing uncrewed systems operations in licensed bands, will require. The talk closes with a forward-looking discussion of how 6G, combined with embedded spectrum intelligence, can serve as the communications backbone for autonomous uncrewed systems ecosystems, enabling safe coexistence, resilient connectivity, and real-time threat response across complex, multi-stakeholder spectrum <a href="http://environments.Bio:" target="_blank" title="environments.Bio:">environments.Bio: Burak Kantarci is a Full Professor and University Research Chair of AI-Enabled Secure Networking for Smart Critical Infrastructures in the Faculty of Engineering at the University of Ottawa.

Low-Earth orbiting (LEO) satellites are now providing broadband service to users around the world. But they face space congestion problems.

Abstract:The demand for continuous increase in the bandwidth of optical transceivers creates a need for technological innovation of photonic integrated circuits (PICs). In particular, the modulators are often the limiting electro-optic component.

Frequency-Domain Cross-Layer Diversity Techniques - Efficient Ways of Coping with Lost Packets in Broadband Wireless SystemsThe design of broadband wireless communications presents considerable challenges. The propagation conditions can be very hostile (e.g., highly dispersive channels and/or deep fading or shadowing effects). This is especially true for systems operating in mm-wave conditions, where one must rely in LoS and/or reflected rays. Moreover, these systems are expected to have power and spectral efficiencies, together with high QoS requirements. There are also implementation complexity constraints, especially at the mobile <a href="http://terminals.Prefix-assisted" target="_blank" title="terminals.Prefix-assisted">terminals.Prefix-assisted block transmission techniques combined with frequency-domain detection are known to be suitable for high rate transmission over severely time-dispersive channels. The most popular modulations based on this concept are OFDM (Orthogonal Frequency-Division Multiplexing) and SC-FDE (Single-Carrier with Frequency-Domain Equalization). However, the severe propagation conditions in multiuser wireless systems make it likely that a non-negligible fraction of the transmitted packets will be lost, either due to deep fading/shadowing effects or due to collisions in the MAC (Medium Access Control) <a href="http://phase.The" target="_blank" title="phase.The">phase.The traditional approach to cope with lost packets is to drop them and ask for its retransmission. However, even packets with a large number of bit errors have useful information on the transmitted blocks that can be employed to improve the detection performance. To take advantage of this, we need to employ a cross-layer approach combining PHY, MAC and LLC layer aspects to cope with lost packets. In this talk we show how we can design powerful cross-layer network diversity techniques specially designed for broadband wireless systems employing block transmission techniques combined with frequency domain <a href="http://detection.Room:" target="_blank" title="detection.Room:">detection.Room: 430, Bldg: EOW, 3800 Finnerty Road, Room 110 Saunders Annex, Victoria, British Columbia, Canada, V8P5C2

Abstract: Future 6G wireless communication systems will require high spectral and energy efficiencies for both economic and environmental reasons. Current amplifiers can have very low amplification efficiency, especially when used with variable-envelope broadband signals like the OFDM-based schemes and single-carrier schemes with compact spectrum (both widely employed in broadband wireless land and satellite communications). In fact, the maximum amplification efficiency for quasi-linear amplifiers (like class-A amplifiers) is 50%. This value drops to 5-10% when high-PAPR signals are employed. By using strongly nonlinear, switched amplifiers (like class D or F amplifiers), we can increase the maximum theoretical amplification to 100%, but the strong nonlinear distortion levels preclude its use with variable-envelope <a href="http://signals.In" target="_blank" title="signals.In">signals.In this presentation, we make an overview on block transmission techniques for broadband wireless communications, as well as current power amplification schemes, with their advantages and limitations when employed with variable-envelope signals. We also present an innovative and highly disruptive amplification scheme named quantized digital amplification (QDA), which can overcome those limitations. It is shown that the QDA allows a quasi-linear amplification of variable-envelope signals like OFDM ones, while maintaining very high energy efficiency, being able to fulfill the spectral masks and EVM (Error Vector Magnitude) requirements of the most demanding wireless systems, including OFDM-based MIMO systems employing large QAM constellations. The power efficiency gains of the QDA allow significant improvements in bit rates and coverage for wireless systems in <a href="http://general.Room:" target="_blank" title="general.Room:">general.Room: MCLD 3038, Bldg: Hector J.
