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

The global nuclear industry is seeing a nuclear resurgence driven by growing electricity demands and advancements in life-saving medical isotopes. This has created an urgent demand for advanced nuclear research infrastructure and training in Canada and around the <a href="http://world.McMaster" target="_blank" title="world.McMaster">world.McMaster University as Canada’s premier nuclear research and education institution plays a critical role in addressing these needs for Canada. McMaster Nuclear is anchored by a suite of world-class facilities that drive innovation in energy, medicine, and materials science. At the heart of this ecosystem is the country’s most powerful research reactor (the McMaster Nuclear Reactor, MNR). Recent investments are enabling first the MNR transition to 24/5 in 2024 and in early 2027 to 24/7. Maximizing the use of the MNR and associated nuclear research facilities has enhanced the university’s research and training capacity.

The concept of Virtual Power Plants (VPPs) has emerged as a promising approach to manage the growing operational challenges associated with high penetration of distributed energy resources (DERs) in distribution systems. By aggregating distributed assets, VPPs enable coordinated control of flexible resources at the customer level. However, in an open market environment where multiple VPPs may coexist within the same distribution network, new technical challenges arise in ensuring secure and reliable operation. In particular, the coordination of multiple VPPs must account for network constraints across the distribution <a href="http://feeder.To" target="_blank" title="feeder.To">feeder.To address these challenges, this work proposes a two-layer VPP dispatch framework. The upper layer determines feasible operating envelopes for each VPP by solving a network-constrained optimal power flow problem, capturing the impact of aggregated resources on the distribution system. The lower layer performs VPP-level dispatch within these limits, ensuring that individual resource schedules remain compliant with network constraints. This framework enables scalable and coordinated deployment of multiple VPPs while maintaining system reliability and operational <a href="http://feasibility.Co-sponsored" target="_blank" title="feasibility.Co-sponsored">feasibility.Co-sponsored by: Resilience and Clean Energy Systems (RCES)Speaker(s): Imantha Meegasthanne Virtual: https://events.vtools.ieee.org/m/553741

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.

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
