Crosscorrelation functions of amplitude-distorted gaussian signals

TL;DR: Bussgang decomposition is utilized to derive downlink signal-to-quantization-plus-interference-plus-interference-plus-noise ratio (SQINR) and ergodic achievable rate expressions under one-bit quantized maximum ratio transmission (MRT) and zero-forcing (ZF) precoding schemes considering scenarios with and without pilot contamination (PC) in the derived channel estimates.

TL;DR: In this article, the authors characterized the rate achievable in a bidirectional quasi-static link where several user equipments communicate with a massive MIMO base station (BS) in full-digital mode, and the physical size of the antenna array is limited, and there exists a rate constraint on the fronthaul interface connecting the radio head to the digital baseband processing unit.

TL;DR: Simulations show that the proposed design of the automatic gain control and low-resolution aware linear receive filter for large-scale multi-user multiple-input multiple-output systems with coarsely quantized signals in cloud radio access networks has better error rates and higher achievable rates than existing techniques.
