摘要： 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.通过仿真验证了新的交织映射算法具有良好的性能.

Abstract: 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. It is proved that the performance of the new algorithm is well by simulation.

Key words: Turbo code, quadratic congruence, interleaver, algebraic mapping
