Pattern Division Random Access (PDRA) for M2M Communications with Massive MIMO Systems
Xiaoming Dai, Tiantian Yan, Qianqian Li +2
In this work, we introduce the pattern-domain pilot design paradigm based on a "superposition of orthogonal-building-blocks" with significantly larger contention space to enhance t…

On the Design of Capacity-Achieving Distributions for Discrete-Time Poisson Channel with Low-Precision ADCs
Qianqian Li, Lintao Li, Lixiang Liu +5
This paper investigates the design of the capacity-achieving input distribution for the discrete-time Poisson channel (DTPC) under dark current effects with low-precision analog-to…
