Pilot contamination, caused by the reuse of pilots among interfering cells, remains a
significant obstacle that limits the performance of massive multi-input multi-output antenna …

Two novel multi-cell precoding schemes, maximum ratio combining precoding with base
station cooperation (MRC-BSC) and zero forcing precoding with BS cooperation (ZF-BSC) …

Pilot reuse in the multi-cell massive multi-input multi-output system is investigated where
user groups with different priorities exist. Recent investigation on pilot reuse has revealed …

In modern wireless communication systems, orthogonal pilot signals has been generally
