Encoding and Decoding for mmWave Massive MIMO Systems

Millimeter-wave (mmWave) and massive multiple-input multiple-output (MIMO) are novel technologies to achieve a satisfactory data rate (up to Giga bits per second) needed by fifth generation (5G) communication systems. There are differences between the signal processing required in high and low frequencies such as hardware limitations and channel models. This paper presents the potential mmWave massive MIMO architecture. It also reviews the up-to-date receivers' structure proposed in mmWave massive MIMO systems. In addition, the paper presents the limitations and differences between the existing algorithms like the maximum ratio combining (MRC), the equal gain combining (EGC) and the iterative block decision feedback equalization (IB-DFE).
