Effect of composite channel aging on the spectral efficiency of multi-pair massive multiple-input multiple-output amplify-and-forward relay networks.

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 perf...
