| 摘 要： | 为了克服水声信道时变多途的影响和基于统计特性的线性均衡(LE)算法收敛后稳态误差大的缺点,提出了基于正交小波变换(OWT)的判决引导联合盲均衡算法(OWT-LE+DD).该算法将OWT理论引入,充分利用OWT良好的去相关性,加快了收敛速度,并采用软判决的方式与判决引导(DD)算法相结合,纠正信道引入的载波相位旋转,减小了稳态误差。水声信道的仿真结果,表明了算法的有效性。

| Abstract: | For greatly overcoming the influence of time-varying from multi-path underwater acoustic channels on the received signal phase and large mean square error(MSE) at convergent end of linear equalizer(LE) based on statistical equalization, A new algorithm of OWT-LE+DD was proposed by joining orthogonal wavelet transform(OWT) with LE,which joins with decision directed(DD).The joining of OWT and LE can efficiently improve convergence rate due to the de-correlation ability of wavelet transform,the joining of OWT-... |
