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。
In this paper, we propose a class of soft interference cancellation iterative detection algorithm combined with iterative decoding of turbo codes in the framework of the MTSS system with bit-interleaved turbo codes. In the first test, a multi-stage serial soft interference cancellation method based on matched filter (M F) was used, and a single-stage parallel soft interference cancellation method was used in subsequent detection. In this paper, iterative detection is combined with iterative decoding of turbo codes, which greatly reduces the number of iterative decoding required for each joint detection of turbo decoding.
