| 摘 要： | 在分析LDPC-Turbo级联码的性能、译码复杂性和时延性的基础上,提出了一种可以提高LDPC-Turbo级联码性能的优化设计,即在LDPC编码器和Turbo编码器之间使用交织器。仿真结果表明,改进后LDPC-Turbo码不仅可以提高性能,而且可以有效地减少平均迭代次数和译码时延,尤其是在大信噪比时,效果更好。

| Abstract: | On the basis of analyzing the performance,decoding complexity and decoding delay of LDPC-Turbo concatenated code,an optimal design of improving the performance of LDPC-Turbo concatenated code is proposed,that is to say the interleaver is used between LDPC encoder and Turbo encoder.The simulation result shows that it can not only improve the performance,but also effectively reduce the average number of iterations and decoding delay,especially in large SNR. |
