講座內(nèi)容：

Massive MIMO and full-duplex (FD) relaying are both key enabling technologies for 5G/B5G wireless communications. In this talk, we look into the feasibility of using low-resolution analog-to-digital converters (ADCs) at multipair FD relay stations with massive antenna arrays. The main challenge lies in that the quantization noise generated by low-resolution ADCs will be exacerbated by the powerful loop interference in FD relaying. More specifically, we analyse the spectral- and energy-efficiency of a multipair FD decode-and-forward relay system with low-resolution ADCs. Based on the mathematical analysis, we propose a novel iterative power allocation scheme to maximize the end-to-end achievable rate by adjusting the per-link transmit power at the relay while mitigating the impact of the quantization noise. Our numerical results show that using FD relaying with the proposed power allocation scheme improves the system throughput and energy efficiency significantly.
