| 摘 要： | 针对复杂多变、强多途和起伏干扰的浅海水声信道,建立了基于BELLHOP射线模型的时变衰落水声信道模型。在此基础上通过系统仿真的方法,分析了卷积码、RS码和串行级联码3种纠错编码方案在水声跳频通信系统中的性能,给出了信道下的仿真结果并进行了对比分析;研究了交织器位置对串行级联码纠错性能的影响。结果表明,交织器位于串行级联码编码之后具有更强的纠错能力,适合复杂多变的水声衰落信道。

| Abstract: | In order to simulate the complex time variant multi-path and fluctuation of shallow water acoustic communication channels,a time-variant multi-path fading channel model based on BELLHOP ray model is established.Three ECC schemes:convolutional code,RS code and serial concatenated code are proposed,the performance of the ECC schemes in underwater acoustic frequency-hopping communication system is analyzed by simulation.Besides,the performance of the different local interleaves in the serial concatenated code ... |
