Hardware Implementation of Fixed-Point Decoder for Low-Density Lattice Codes
(University of Waterloo, 2022-04-29)Low-density lattice codes (LDLCs) are a special class of lattice codes that can be decoded efficiently using iterative decoding and approach the capacity of the additive white Gaussian noise (AWGN) channel. The construction ... -
Hardware-Aware Precoding and Digital Predistortion for Massive MIMO Transmitters
(University of Waterloo, 2022-05-19)To cope with the ever-increasing demand for higher data rates, reduced latency, and improved coverage, new technologies are needed to advance the current state of wireless communication systems. One of the promising new ... -
On Capacity-Achieving Input Distributions to Additive Vector Gaussian Noise Channels Under Peak and Even Moment Constraints
(University of Waterloo, 2021-08-25)We investigate the support of the capacity-achieving input distribution to a vector-valued Gaussian noise channel. The input is subject to a radial even-moment constraint and, in some cases, is additionally restricted ... -
On Optimal Online Policies in Energy Harvesting Communication Systems: Effects of Quality of Service and Battery Requirements
(University of Waterloo, 2016-04-27)We study the problem of finding optimal transmission policies in a point-to-point energy harvesting communication system with continuous energy arrivals in causal setting. In particular, we investigate bounds on the long-term ... -
Operating multi-user transmission for 5G and beyond cellular systems
(University of Waterloo, 2023-02-16)Every decade, a new generation of cellular networks is released to keep up with the ever-growing demand for data and use cases. Traditionally, cellular networks rely on partitioning radio resources into a set of physical ... -
Performance Limits of Microwave and Dual Microwave/Millimeter Wave Band Networks
(University of Waterloo, 2019-12-11)Traditionally, wireless networks communicate over the conventional microwave band (sub-6 GHz) as it supports reliable communication over a large geographic area. The ever increasing demand for bandwidth to support the ... -
Performance of Massive MIMO with Interference Decoding
(University of Waterloo, 2021-08-06)In a massive MIMO system, base stations (BS) utilize a large number of antennas to simultaneously serve several (single or multi-antenna) users at once, where the number of BS antennas is normally assumed to be significantly ... -
Real-Time FPGA-Based Testbed for Evaluating Digital Predistortion in Fully Digital MIMO Transmitters
(University of Waterloo, 2023-04-27)As one of the key enabling technologies of 5G networks, massive multiple-input, multiple-output (MIMO) transmitters use many transmit chains to ensure a very high data rate and acceptable signal quality. Realizing Massive ... -
Single Input Single Output Digital Pre-Distortion at Millimeter Wave Frequencies for Phased Arrays
(University of Waterloo, 2019-08-30)The limiting fact that is impeding the increase in data rate in the current generation of wireless communication is the limited available spectrum in the sub-6 GHz bands. This has motivated the shift to higher frequencies ...
