| 摘 要： | 以Rimoldi提出的分解方法为基础,文中介绍了一种与连续相位调制CPM(Continuous PhaseModulation)相适应的环卷积编码技术,该编码与CPM内在编码具有相同的代数结构,文中给出了两者结合后的常用研究方法。通过计算机搜索,以最小欧氏距离最大为目标,得到了一些典型参数下最优的编码方案。仿真结果表明,采用环编码后CPM信号的误比特性能有很大的提升。

| Abstract: | Convolutional codes over rings suitable for continuous phase modulation were presented based on the Rimoldi's Decomposition of CPM.Because the codes are on the same ring as the inner codes of CPM,some technologies were used to analyze the overall codes,and some typical codes scheme with maximum Normalized Minimum Squared Euclidean Distance(NMSED) were searched and given.Moreover,simulation result shows that this ring coded CPM is more robust than usual coded CPM. |
