Coded Multi-User Extreme Massive MIMO Systems with Gauss Seidel-Aided MMSE-PIC

This paper discusses the design methodology of a concatenated coding system utilizing Gauss-Seidel-aided MMSE-PIC and LDPC codes, used in extreme massive MIMO systems. The proposed design method enhances the BER (Bit Error Rate) performance convergence speed of the system compared to conventional designs, with reduced computational complexity. To achieve this, the paper tracks the overall data flow of the system and conducts EXIT analysis, predicting BER performance convergence speed, which aligns with actual BER performance through simulation. Therefore, the analysis and design methodology proposed in this paper for LDPC Coded Gauss-Seidel-aided MMSE-PIC systems are expected to play a crucial role in next-generation communication systems (6G) that demand high-speed data processing.
