Performance of 3D Massive MIMO with Transceiver Impairments for K Composite Fading Channel

摘要

Three dimensional massive multi-input multi-output (3D M-MIMO) antennas technology has attracted much attention. Since it can contribute system capacity and cell coverage range. In this work, the sum rate performance of 3D M-MIMO with transceiver impairments in K composite fading channel is studied. Derivation closed expression of sum rate of 3D M-MIMO system based on minimum mean square error (MMSE) receiver with the transceiver impairment and situation of multiple fading coexistence, such as, shadow fading, path loss, 3D antenna radiation loss. The performance of 3D M-MIMO system based on MMSE receiver is obtained. The simulation results show that with transceiver impairments MMSE receiver has better sum rate performance than zero forcing (ZF) receiver. 3D M-MIMO system can be affected by transmission power, the number of BS antennas, shadow fading, path loss, antenna downtilt, the distance between BS and users, and the correctness of the theoretical analysis is proved by Monte Carlo simulation.
