摘要
将单载波块传输系统运用于水声通信中,为了克服信道中存在的深衰落,对基于一种UW字块结构的时频域混合判决反馈均衡和块迭代频域判决反馈均衡两种判决反馈均衡的方法进行了比较和分析。仿真结果及水池实验表明:基于该UW字结构的块迭代频域判决反馈均衡在水声通信中有良好的应用前景。
In order to overcome the deep fading caused by the multipath propagation in the underwater acoustic enviroment which hugely destroys the performance of the single carrier system, we proposed, compared and analysed time frequency hybrid feedback equalizer （HDFE） and iterative block decision feedback equalization （IBDFE） based on a kind of unique word （UW） block structure. Simulation results and pool test indicate that IBDFE based on the unique word block structure is a pro-mising technique in the underwater acoustic communication.
