摘要
首先分析确定性交织器的映射原理,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,结果表明,在复杂度可比的情况下,改进后的交织器比原交织器具有更好的译码性能。
In this thesis, mapping theory of certain interleaver is analyzed firstly. Based on this, keeping the limit of odd and even queues and doing shifting operations are done on mapping relationships of the interleaver. Thereby, two improved mapping interleaving algorithms are achieved. Performance of improved interleavers is tested through emluator and the result shows that improved interleavers have better coding performance than primary ones under the circumstance of comparable complicated degree.
