| 摘 要： | 本文在比特交织turbo编码调制的空分复用M IMO系统发送框架下,研究了一类与Turbo码的迭代译码联合进行的软干扰抵消迭代检测算法。在首次检测中,使用了基于匹配滤波(M F)的多级串行软干扰抵消方法,在后续的检测中使用了单级并行软干扰抵消方法。本文又把迭代检测同turbo码的迭代译码联合,大大降低了每次联合检测turbo译码需要的迭代译码次数。

| Abstract: | In MIMO system,which employs bit interleaving,turbo encoding and modulation and space-division multiplex techniques,this paper explores the algorithm of the iterative detector which is based on soft-interference-cancellation and associated with the iterative decoding of turbo code. In the first-time detection,multi-level successive soft interference cancellation based upon matched-filter(MF) is applied,and in the following detection single-level parallel soft interference cancellation technique is employed.Also,iterative detection and iterative-decoding of turbo-code are joined together in this thesis,from which the iteration-time of turbo decoding in the joint-detection is notability reduced. |
