| 摘 要： | 本文改进了概率数据辅助(probabilistic data association,PDA)算法,将其应用于MIMO(multiple-input multi- ple-output)系统中,并提出了一种partial-PDA LDPC联合检测算法,比PDA LDPC联合检测算法的计算复杂度更低。计算机仿真结果显示,partial-PDA LDPC联合检测算法能够取得非常接近于PDA LDPC联合检测算法的系统性能。

| Abstract: | In this paper,we derive a modified probabilistic data association(PDA)algorithm for MIMO channels,and present a partial-PDA LDPC joint detection algorithm,which has a low computational complexity than the PDA LDPC joint detection algorithm. Simulation results show that,the performance of partiaI-PDA LDPC joint detection algorithm can well approximate to that of the PDA LDPC joint detection algorithm. |
