本文探讨了无线移动信道中空时格形码的一种自适应解码技术.通过分析无周期间插正交导引信号下空时格形码的最大似然序列检测
指出可利用逐幸存路径处理得到该情形下可实用的最大似然序列检测算法;以此为依据
结合利用自调整LMS算法实现的信道跟踪
本文提出一种空时格形码的自适应解码器
该解码器具有所采用信道跟踪参数与信道衰落速度无关的优点;文章最后给出计算机仿真结果.
The problem of adaptive decoding of space-time trellis code (STTC) on the mobile wireless channels is considered in this paper.After analyzing the maximum likelihood sequence detection (MLSD) of STTC transmission burst with no periodically inserted pilot symbols
we show that per-survivor processing (PSP) can be used to obtain a practical approximated MLSD in this situation.Based on this
a PSP decoder with self-tuning Least-Mean-Square channel tracking is proposed with the advantage that there are only fading rate independent parameters to be pre-determined.Computer simulation results are included to support our development.
