摘要

本文提出一种针对空时格形码的软判决自适应双向解码算法.通过执行双向解码

该解码算法充分利用了TDMA下行链路相邻时隙的前导序列

并给出高质量的软判决解码输出;同时

所提出的两步最小均方算法以较低的运算开销实现了对时变信道的自适应跟踪.文章最后给出计算机仿真结果.

Abstract

A new soft-decision adaptive decoding algorithm for space-time trellis code (STTC) is proposed.With a bidirectional decoding (BD) structure

the proposed algorithm fully utilizes the preambles of adjacent TDMA downlink slots and produces high-quality soft-decision output.Besides

two-step Least-Mean-Square (TSLMS) algorithm is developed to implement simple but effective channel tracking in each unidirectional decoding.Computer simulation results are given to support our development.
