This study investigates the spectral efficiency of multi-pair massive multiple-input multiple-output amplify-and-forward relay networks by considering the composite channel aging effect. The rational of this work is that the channel aging effect caused by phase noise and node movements is an inevitable practical channel impairment in time-varying fading channels and substantially degrades the performance...
We investigate pilot contamination problem for very large MIMO multi-cell TDD system. The asymptotic sum rate of two typical precoding schemes, i.e., the single-cell zero forcing (ZF) precoding and the multi-cell minimum mean square error (MMSE) based coordinated precoding are first derived. Results show that these two schemes have the same asymptotic sum rate expression as the number of the base...
