【摘要】 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.更多还原

【Abstract】 Based on the document [2], this article adds a generalized adaptive link between demodulating and decoding.Its decoding operation in the co-designing system is generalized adaptive in the sense that the transition metric according to the constellation and the surviving path by which the decoder looking back is all dynamic adjusted.Thus this kind of design improves the total performance of the system.After giving models of the system, the article gives a result of computer simulation.更多还原
