title = "Low-complexity iterative PIC-MMSE based detection with symbol mapping",
abstract = "The iterative detection and decoding technique based on parallel interference cancellation (PIC) has received considerable attention. To reduce the computational complexity in the estimation of soft bit information, this paper proposes to apply the symbol mapping technique to the PIC-MMSE based MIMO detector. In each layer, the PIC-MMSE filtered symbol is normalized and mapped to a specific range of the first quadrant in a recursive manner. In addition, we present an efficient method to calculate the soft symbols in the PIC process. Simulation results show that the complexity of the proposed method with symbol mapping is reduced to linear-order without performance degradation, and the complexity of the soft symbols computation is greatly reduced as well.",
