Abstract: The paper presents a novel hybrid precoding scheme, named group-and-codebook based two-timescale hybrid precoding (GC-THP), for millimeter wave (mmWave) massive MIMO Systems. This scheme ...

Abstract: This paper deals with the practical precoding design for a two-hop downlink with MIMO amplify-and-forward relaying. A novel scheme of codebook-based joint precoding at both the base station ...
