| 摘 要： | 针对传统的常数模盲均衡算法(CMA)收敛速度慢、稳态误差大和局部收敛的缺点,提出了一种基于遗传优化的正交小波分数间隔盲均衡算法(WT-FSE-GA).该算法通过对分数间隔均衡器的输入信号进行正交小波变换,以降低信号的自相关性,并利用遗传算法全局随机搜索的特性,对均衡器权向量进行优化,以降低CMA陷入局部收敛的可能性.与...

| Abstract: | Aimed at some disadvantages of traditional constant modulus blind equalization algorithm(CMA),such as low convergence speed,large steady-state error and local convergence,an orthogonal wavelet transform fractionally spaced blind equalization algorithm based on genetic optimization algorithm(WT-FSE-GA) is proposed.It can reduce the signal autocorrelation by orthogonal wavelet transform to input signal of fractionally spaced blind equalizer.And,it can also reduce the possibility of CMA's local convergence usi... |
