摘要
设计了一种新的不等行列交叉循环交织器,该交织器能够克服分组交织器消除相关性不彻底的缺陷,同时也能很好地解决随机交织器重置低重量输入序列效果不明显的问题.仿真结果显示:将新型交织器用于Turbo码无线图像传输系统,可以获得更好的重建图像质量,表明新型交织器具有比分组和随机交织器更好的性能.
This study presents a novel design approach for the interleaver,named unequal row-column cyclic cross interleaver.This interleaver can eliminate the more information correlation than that of block interleaver.It can also permute the low weight codeword sequence effectively.Simulation results show that the proposed interleaver in Turbo codes can reconstruct the better image quality in wireless image transmission systems,and the performance is better than that of block interleaver and random interleaver.
