Multifunctional Filtering AntennasJawad Y. SiddiquiUniversity of Calcutta, Queen's University and Royal Military College of CanadaSummary:Modern RF systems often require multiple antennas to support various frequency bands. Reconfigurable antennas address this need by providing frequency agility, compact size, and reduced hardware complexity. The proposed antenna achieves this through electrical reconfiguration enabled by the embedded SRRs and PIN <a href="http://diodes.The" target="_blank" title="diodes.The">diodes.The techniques proposed in this work have been implemented on two types of UWB antennas, a printed monopole antenna and a printed antipodal tapered slot antenna (ATSA) to validate the concept on radiators with distinct radiation characteristics: omnidirectional and directional, respectively. In both cases, split ring resonators (SRRs), magnetically coupled to the CPW feed line, function as band-stop filters, introducing a frequency notch in the UWB response around their resonance. When a set of PIN diodes embedded in the feed line are forward biased (ON), the antenna transforms into a narrowband band-pass filter centered at the same resonance frequency, thereby realizing complementary frequency responses from a single antenna <a href="http://structure.A" target="_blank" title="structure.A">structure.A key feature of the design is that it preserves the original radiator geometry. The work demonstrates a compact, versatile, and effective approach to achieving multifunctionality in UWB antennas. The integration of reconfigurable filtering into the feedline enables real-time switching between wideband and narrowband operation, making the design especially suitable for cognitive radio, multi-standard wireless systems, and MIMO <a href="http://applications.Speaker(s):" target="_blank" title="applications.Speaker(s):">applications.Speaker(s): Dr. JawadRoom: EIT-3151, Bldg: EIT, 200 University Ave W, Waterloo, Ontario, Canada, N2L 3G1, Virtual: https://events.vtools.ieee.org/m/553628

Modern satellite communication systems operate in highly dynamic and non-ideal propagation environments, where performance is strongly impacted by a combination of deterministic and stochastic impairments. These include atmospheric attenuation (rain fade, gaseous absorption), Doppler shifts due to platform mobility, phase noise, group delay distortion, non-linearities from high-power amplifiers, and multipath effects in certain scenarios (e.g., maritime or urban reflections for LEO systems).This talk presents how advanced RF channel emulators can be used to accurately reproduce these real-world satellite impairments in a controlled laboratory environment. The objective is to enable repeatable, scalable, and high-fidelity testing of satellite links, terminals, and subsystems without relying on costly and time-constrained over-the-air experiments. The presentation will cover: Physical-layer impairment modeling, Implementation in channel emulators, Test and validation workflows, and Use cases, including validation of adaptive coding and modulation (ACM), beam tracking algorithms, and interference resilience in next-generation satellite systems (e.g., HTS and non-terrestrial networks for 5G/6G). Particular attention will be given to the challenges associated with wideband and high-frequency systems (Ka-/Q-/V-band), where impairments are more pronounced and system margins are <a href="http://tighter.By" target="_blank" title="tighter.By">tighter.By bridging the gap between theoretical channel models and practical system validation, channel emulation emerges as a critical tool for accelerating the development and certification of robust satellite communication <a href="http://technologies.Co-sponsored" target="_blank" title="technologies.Co-sponsored">technologies.Co-sponsored by: INRS/StaracomAgenda: 10 h-12 h : Talk & Discussion12h: PizzaRoom: 6900, Bldg: 6900, 800 Rue De la Gauchetière Ouest, Montréal, Quebec, Canada, H5A 1K8

Abstract: AI is changing not only the applications we build, but also the way we design the chips that power them. This talk explores how we can rethink chip design in the age of AI from two complementary directions: using AI to automate and improve chip design, and building specialized chips that make AI dramatically more <a href="http://efficient.On" target="_blank" title="efficient.On">efficient.On the design side, we present Agentic-RL gLayout, a reinforcement-learning framework for analog layout generation that replaces manual heuristics with goal-driven planning and self-correction. Built on open-source tools such as OpenROAD, gLayout, and OpenFASOC, it enables cleaner, more compact, and rule-compliant layouts with far less manual effort. On the architecture side, we present a hardware-software co-design stack for efficient edge AI, reducing latency and energy in LLM inference. By co-optimizing models, precision, and accelerator design, this approach supports fast, privacy-preserving inference under tight power <a href="http://constraints.Taken" target="_blank" title="constraints.Taken">constraints.Taken together, these efforts illustrate a broader shift toward open, AI-enabled chip design flows and domain-specific AI hardware.

Title: Generative AI and Deep Learning for Resource Allocation in 6G Wireless NetworksAbstract:This talk provides an in-depth exploration of resource management in 6G wireless networks, focusing on the vision, key performance indicators (KPIs), key enabling techniques (KETs), and the diverse array of services characteristic of these advanced networks. The distinct challenges inherent in 6G resource management call for a pivotal shift toward artificial intelligence (AI) and machine learning (ML)–driven solutions, requiring a departure from traditional optimization-centric <a href="http://approaches.The" target="_blank" title="approaches.The">approaches.The talk sheds light on generative AI and unsupervised ML strategies tailored to effectively address convex and non-convex resource management optimization problems. A key focus is placed on deep unsupervised learning techniques for network resource allocation under nonlinear and non-convex constraints. Deep implicit layers and differentiable projection methods are explored as mechanisms to ensure zero constraint violations in applications such as beamforming, phase-shift optimization, and power <a href="http://allocation.Furthermore" target="_blank" title="allocation.Furthermore">allocation.Furthermore, the potential of generative AI models, including large language models (LLMs), to enable proactive network resource allocation is examined, highlighting their role in optimizing performance and reducing reliance on traditional heuristics.

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 <a href="http://vision.Room:" target="_blank" title="vision.Room:">vision.Room: MCLD 3038, Bldg: Hector J.
