Abstract

本发明涉及一种发射系统、接收系统及其组成的编码调制解调系统，及其信号的发射和接收方法，通过将准备进行多阶QAM调制的信源经过处理分为若干个分信源进行独立的QPSK调制，并通过串行干扰对消叠代的解调系统，将多阶QAM的解调分解为串行对消的若干级QPSK解调。使得接收机原来对高阶正交幅度解调所需要的较高的信干比转换为只需要QPSK解调所需要较低的信干比，从而带来了解调增益。同时在保证通信质量的前提下，由于QPSK的解调明显的比高阶正交幅度调制简单，从而有效改善了多阶QAM调制解调的实现复杂度。同时，通过对不同星座位置的信息进行不平衡的前向编码冗余处理，有效利用星座之间的信干比和质量的不平衡性，从整体上提高了编码效率。
