| 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，从而得到两个改进型的算术映射交织算法。通过仿真对改进型交织器的性能进行验证，结果说明在复杂度可比的情况下，改进后的交织器比传统分组交织器具有更好的译码性能。 |

| Abstract: |
| At first, 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. Two new improved interleaving algorithms are obtained. It is proved that the performance of the improved interleaver is better than the traditional block interleaver under comparable complexity by simulation. |
