1-bit Nonlinear Mapping Precoder for Downlink Massive MU-MIMO Systems
2021 30th Wireless and Optical Communications Conference (WOCC)（2021）
摘要
This paper studies a downlink massive multiuser multiple-input multiple-output system with PSK modulation, where the base station employs 1-bit digital-to-analog converters (DACs). We first exploit the concept of constructive interference (CI) to express the received PSK signal in terms of the coordinate vector. With the coordinate vector, we construct a nonlinear mapping (NM) function in which th...
