| 摘 要： | 提出一种基于硬判决BICM-ID系统中的迭代盲信道估计算法.该算法基于最大似然估计(ML)同步算法,利用BICM-ID译码产生的硬判决信息,通过迭代地在信道估计和解码之间交换信息来完成联合信道估计和解码.仿真结果验证了算法的有效性,并分析了信噪比和块衰落信道的块长对迭代信道估计性能的影响.

| Abstract: | An iterative ML-based iterative channel estimation algorithm in BICM-ID was proposed based on hard-decision,which made use of the hard-decision information provided by the iterative decoder and got good channel estimation by iteratively exchanging information between the channel estimator and decoder. Simulation results show the proposed method is effective,SNR and the block length of block fading channels on performance of the proposed algorithms was analyzed. |
