本文是在文献[2]的基础上在解调与译码间加入了一个广义自适应环节,通过动态调整依据信号星座图计算的分支量度及译码回溯的幸存路径来实现联合设计中译码的广义自适应,以进一步提高系统的总体性能.文章在给出系统模型后,给出了计算机模拟的结果.
Based on the literature [2], this paper adds a generalized adaptive link between demodulation and decoding, and realizes the decoding in joint design by dynamically adjusting the branch metric calculated according to the signal constellation and the surviving path of decoding traceback In order to further improve the overall performance of the system.After the system model is given, the results of computer simulation are given.
