| 摘 要： | 基于M进制正交调制的软比特输出特性，对不同编码条件下的M进制正交调制性能进行了仿真评估。结果表明，与二进制卷积码和Turbo码相比，非二进制双k码作为一种误比特率、计算量及译码时延的折衷方案，可以应用于正交调制系统。

| Abstract: | The performances of different coded M-ary orthogonal modulation are simulated and evaluated on the basis of the soft bits output of M-ary orthogonal modulation. The simulation results show that, compared with binary convolutional codes and Turbo codes, nonbinary dual-k codes can be regarded as a tradeoff among bit error rate (BER), computations and decoding time delay, and it can be applied to M-ary orthogonal modulation systems. |

| Keywords: | orthogonal modulation convolutional codes nonbinary dual-k codes turbo codes |
