| 摘 要： | 基于Turbo乘积码的编译码原理,利用Matlab仿真工具,对以(64,57,4)扩展汉明码为子码的Turbo乘积码进行迭代次数、量化比特数等不同参数的性能仿真,根据仿真结果选取最佳的设计参数,同时通过仿真给出了Turbo乘积码在衰落信道中的应用效果。结合Matlab仿真,在Quartus环境中完成编译码算法的硬件设计与调试,并将其应用到无线通信调制解调器中。测试结果表明,Turbo乘积码显著改善了调制解调器在衰落信道中的误码性能。

| Abstract: | Based on the encoding and decoding principle of Turbo product code, the performance of the turbo product using extended Hamming codes is simulated by the software Matlab on different iteration number, numbers of quantification bit and other parameters. The optimal design parameters are selected according to the simulation results, and the application effect of turbo product code in the fading channel is given. With the Matlab simulation, the hardware design and debugging of the encoding and decoding algorithm in the software Quartus is completed, and is used in wireless communication modem. The test results show turbo product code improves greatly the BER performance of the modem in the fading channel. |
