A Remark on Downlink Massive Random Access
Yuchen Liao, Wenyi Zhang
In downlink massive random access (DMRA), a base station transmits messages to a typically small subset of active users, selected randomly from a massive number of total users. Exp…
An Information-Theoretic Framework for Receiver Quantization in Communication
Jing Zhou, Shuqin Pang, Wenyi Zhang
We investigate information-theoretic limits and design of communication under receiver quantization. Unlike most existing studies, this work is more focused on the impact of resolu…
A High-Resolution Analysis of Receiver Quantization in Communication
Jing Zhou, Shuqin Pang, Wenyi Zhang
We investigate performance limits and design of communication in the presence of uniform output quantization with moderate to high resolution. Under independent and identically dis…
Information Rates of Channels with Additive White Cauchy Noise
Shuqin Pang, Wenyi Zhang
Information transmission over discrete-time channels with memoryless additive noise obeying a Cauchy, rather than Gaussian, distribution, are studied. The channel input satisfies a…
Generalized Nearest Neighbor Decoding: General Input Constellation and a Case Study of Interference Suppression
Shuqin Pang, Wenyi Zhang
In this work, generalized nearest neighbor decoding (GNND), a recently proposed receiver architecture, is studied for channels under general input constellations, and multiuser upl…
