将多级调制时, 映射到同一符号的不同比特具有不同可靠性的特性引入软输出高阶解调算法中, 推导出一套

简单易行的通用算法, 使得在任何格雷映射方式下, 都能够使用一组相同的两级递推公式计算比特软判决信息。提供了一种

具有低复杂度的通用的高性能软输出高阶解调算法。-Multi-level modulation, the symbols are mapped to the same bit different with different characteristics of the reliability of the introduction of high-end soft-output demodulation algorithm, derived from a simple generic algorithm, the Gray mapping in any manner that they are able to the use of a group of the same recursive formula for calculating the two-bit soft-decision information. Provides a low-complexity high-performance general-purpose high-end soft-output demodulation algorithm.
