Spatially Correlated Massive MIMO Relay Systems with Low-Resolution ADCs
IEEE Transactions on Vehicular Technology（2020）
Abstract
In this paper, we investigate the massive MIMO relay system, where the relay station (RS) forwards the signals from multiple remote users to the base station (BS). Large-scale antenna arrays in conjunction with low-resolution analog-to-digital converters (ADCs) are equipped at the RS and the BS to guarantee the high spectral efficiency with low cost. Considering the ever-present spatial correlatio...
