基于全交织的Turbo码方案

A Turbo code scheme based on fully-interleaved encoder

根据Turbo码编码器的组成及码序列交织的原理 ,提出了一种全交织的Turbo码方案 .码距离分析表明 ,该方案能减少输出码组中最小汉明距离码字的分布 ,提高系统对突发误差的抗干扰能力 .仿真结果显示 ,采用该方案可得到 0 .5dB左右的最大编码增益 .

Based on the structure of Turbo encoder and the principle of interleavers, a new turbo code scheme with a fully interleaved encoder is proposed, which can be proved that this scheme is able to decrease the number of the codewords with the minimum Hamming distance and obtain better performance to deal with the burst errors. Given simulations show that Turbo codes can achieve 0.5 dB asymptotic gain by this way.
