quadratic congruence

Based on the quadratic congruence interleaver, a new algorithm which is improved on the linear congruence is advanced, the choices of its parameters are analyzed systematically and The new algorithm has the effects on the low weight codewords distribution.

基于二次算术同余交织器的构造算法，提出了对线性同余交织器的改进，系统地分析了其参数的选择情况及对低码重分布的影响。

The principle of algebraic quadratic congruence mapping is analysed, and then limitation of odd even protection and shift computation are added to the mapping of interleaver, and then a new improved algorithm for interleaver design is obtained.

首先分析算术二次同余映射的原理，然后在此基础上对交织器的映射关系加以保奇偶序限制和移位运算，得到改进的交织映射算法。
