Coded MIMO Detection Based on Iterative Channel Soft Information
基于迭代信道软信息的编码MIMO检测

In this paper, the influence of error propagation on soft demodulation in coded MIMO system is analyzed in detail. Besides, based on the thought of soft symbol interference cancellation, Iterative Channel Soft Information (ICSI) for coded MIMO system is further deduced and proved to have the same form as the inverse of row norm of Moore-Penrose inverse of channel matrix. Theoretical analysis and simulation results indicate that the proposed coded MIMO detection algorithm based on ICSI could improve the system performance effectively without additional calculation complexity.
