Recently, the iterative detection and decoding technique based on parallel interference cancellation with minimum mean square error (PIC-MMSE) has received considerable attention. To improve the performance, the detector usually adopts a self-iteration which iteratively estimate the soft bit information (SBI). This paper proposes two main idea to improve the performance as well as to reduce the complexity...
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...
