| 摘 要： | 为了克服常模算法(CMA)收敛速度慢的缺点,提出一种基于平衡正交多小波变换的常模盲均衡算法(MWTCMA)。该算法引入了平衡正交多小波,弥补了多小波在实际应用时必须进行预滤波的缺陷,并推导出了平衡正交多小波变换矩阵的通用表达式。水声信道盲均衡的仿真结果表明:与基于正交小波变换的常模盲均衡算法(WTCMA)和常规CMA相比,该算法的收敛速度得到了显著的提高,均方误差得到了一定的改善。

| Abstract: | In order to overcome the slow convergence rates of constant modulus algorithm(CMA),a balance orthogonal multiwavelet transform based constant modulus blind equalization algorithm(MWTCMA) was proposed.Balance orthogonal a multiwavelet was introduced into the algorithm for compensating the absence of prefiltering to multiwavelet in actual application,and the common form of orthogonal multiwavelet transform matrices was deduced.The simulated results by MWTCMA in underwater acoustic channels show that the propo... |
