摘要

这项工作提出了五进位涡轮编码相位调制。五进位turbo编码调制由两个五进位递归系统卷积编码器、一个带穿刺的交织器和一个混合4-5-PSK调制方案组成。turbo译码过程采用基于最大后验(MAP)译码的5元迭代算法进行。仿真结果表明，五进位的turbo码调制比四进位的四进位turbo码调制具有更好的性能。

5-ary turbo codes with 4-5-PSK modulation

This work presents 5-ary turbo coded phase modulation. 5-ary turbo coded modulation consists of two 5-ary recursive systematic convolutional encoders, an interleaver together with a puncturing and a hybrid 4-5-PSK modulation scheme. The turbo decoding process is performed by a 5-ary iterative algorithm, based on the maximum a posteriori (MAP) decoding. The simulations show that 5-ary turbo coded phase modulation presents better performance than 4-ary (quaternary) turbo codes.
