摘要 将随机数据联合检测算法(PDA)嵌入到EM算法中,提出了一种低复杂度的迭代信道估计算法。其计算复杂度较MAP-EM迭代信道估计算法显著降低,并且仿真结果显示,可取得与MAP-EM算法相近的系统性能。 This paper applied the probabilistic data association algorithm（PDA） in the EM algorithm and developed a low-complexity iterative channel estimation algorithm.The complexity of the proposed algorithm is reduced significantly compared with the MAP-EM algorithm.In addition,simulation results demonstrate that it can approximate the performance of the MAP-EM algorithm.
