摘要 一种Nonbinary-Turbo-DFH系统方案,提出了多进制系统递归卷积码类型的G函数及编译码器结构,并给出了相应的软判决迭代译码算法。Nonbinary-Turbo-DFH改进了Turbo-DFH系统的编译码器结构,使用了新的G函数和相应译码算法,解决了Turbo-DFH系统中缺少系统码跳频信息的问题,仿真结果表明,与传统DFH和Turbo-DFH系统相比,Nonbinary-Turbo-DFH系统具有更好的误比特率性能。 The scheme of Nonbinary-Turbo-DFH system is proposed, a kind of function G based on M-ary Recursive Systematic Convolutional codes is constructed and corresponding soft-decision decoding algorithm deduced. The Nonbinary-Turbo-DFH system modifies the coder and decoder structure of Turbo-DFH, and employs new function G and decoding algorithm to solve the lack of frequency-hop information in Turbo-DFH system. Simulation results indicate that as compared with traditional DFH system and Turbo-DFH system, LDPC-DFH system has even better BER performance.
