摘要 Turbo码是迄今为止性能最为优异的一种信道编码方式 ,是 IMT2 0 0 0信道编码的推荐标准 .本文采用 (7,5 )递归系统卷积码 ,最小距离伪随机交织 ,软输出维特比译码算法在 TMS32 0 C5 4X上实现了 Turbo码 ,并对所实现的 Turbo码在不同信道 ,不同信噪比情况下的的性能指标进行了模拟测试比较 . Turbo code has the best performance for channel coding which is developed recently. It becomes an recommending coding technique for the next-generation wireless communication protocol, such as W-CDMA and 3GPP for IMT-2000. We implement Turbo decoder with (7,5) RSC, pseudo__random interleaving and SOVA using TMS320C54X.
