The solving of Blind equalization in practice is very difficult. For the conventional channel equalization techniques, the channel point-spread function (PSF) must be determined firstly, but it is almost impossible to obtain the PSF in practice.
盲均衡技术实际求解比较困难,一般信道均衡使用传统均衡技术,因而必须首先知道点扩展函数,但实际条件下点扩展函数不可能知道。
