| 摘 要： | 研究了一种基于统计特性均衡准则的判决引导盲均衡结构,以有效克服水声信道多径衰落的不利影响,并针对水声信道的时变多普勒特性,引入数字锁相环技术,提出了一种基于统计特性均衡准则的判决引导盲均衡,与数字锁相环相结合的联合盲均衡算法,以快速纠正信道引入的载波相位旋转,加快算法的收敛速度.仿真结果证明了该算法的有效性.

| Abstract: | Based on equalization criterion of statistics, a new blind equalizer is explored to combat the multi-path fading effects of underwater acoustic channels. Towards the time-varying Doppler underwater acoustic channels, a novel combined blind equalization algorithm including the new blind equalizer and phase-locked loop are proposed, which can efficiently and fast correct the channel-introduced carrier phase rotation and improve the convergence rate. The efficiency of the method is proved by computer simulation in underwater acoustic channels. |
