The 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 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) 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 detection.

Description 💻 Control your world through your programming! Come to our Part I Arduino workshop where you will learn the basics of programming the Arduino, how to use its various features and how to connect your own circuits to the Arduino. Through this handy little microcontroller, you’ll be able to automate tasks and unlock a whole new world of DIY projects to bring your ideas to life! In this workshop, we will provide all the tools you need to start playing around with the Arduino — except a laptop. A subsequent Part II workshop on more advanced Arduino topics will be held two days after. If you want to continue using the Arduino after the workshops, you can come visit the lab or ask us about where to buy the components. ⚠️ Important Info ⚠️ This workshop will cost $5 and payment can be made via e-transfer or cash at the door . There will be free pizza and drinks at the end! 🍕 Please bring your own computer with the Arduino IDE​ installed. Your computer will connect via USB-A to the Arduino. Please bring an adapter if your computer does not have a USB-A port. Room: 1050, Bldg: Wong Building, 3610 University St, Montreal, Quebec, Canada, H3A 0C5

This talk will explore and compare power conversion systems for wireless charging and DC fast charging. The focus will be on understanding the key technologies, efficiency, and practical implications of these systems. The talk will present an in-depth analysis of power conversion systems for both wireless charging and DC fast charging applications. A comprehensive review of existing technologies, their advantages, and limitations will be explained. Optimal solutions for various scenarios, considering efficiency, cost, and environmental impact will also be presented. In essence, the talk will present valuable insights into the evolving field of EV charging infrastructure and wireless power transfer systems.
