摘要
该文从理论上分析了Turbo码的性能特点,探讨了交织器在Tlurbo码中所起的作用,并分析指出交织器设计的主要参考因素。通过对常用交织算法的分析和比较,提出了一种基于三维(3-D)矩阵的低复杂度交织算法,实验结果验证了该算法具有较好的性能。
This paper analyzes theoretically the properties of Turbo codes and the effects of the interleaver. Some elements for devising good interleaver are pointed out in this paper. Compared with some traditional algorithms, a low-complexity method based on three-Dimensional (3-D) matrix is proposed. The simulation results demonstrate its good performance.
