Comparison and analysis of the regularized zero forcing (RZF) precoder, Sherman-Morrison-Woodbury (SMW)-based precoder, rapid numerical algorithms (RNA)-based precoder and the truncated polynomial expansion (TPE)-based precoder are compared and analyzed for massive multiple-input multiple-output (MIMO) wireless system in a downlink scenario. The achievable data rates and signal-to-noise ratio (SNR) were investigated. The simulated outcome agrees with the theory of massive MIMO system. Also the RZF precoder, RNA-based precoder and the SMW-based precoder perform better in comparison to TPE-based precoder under good CSI quality and low ratio of transmit to receive antennas.
