emd算法 主要用来提取信号的本征模态，将信号的原始信号从混合噪声中提取出来(emd algorithm Mainly used to extract the signal intrinsic mode, the original signal from the mixed noise extraction)

leach 仿真算法,本人从别人处得到尚未验证,大家共同讨论(leach simulation algorithm, I have not yet been verified from the others at, we discuss)

We see that HTH matrix is almost diagonal as the off diagonal elements are nearly zero. So we are getting exact estimation in case of PRN INPUT due to diagonality of HTH matrix. As seen that the unknown inpulse response ( h ) and estimated impulse response ( hth ) are coming out to be exactly same. The estimation even gets better for large N .as we get the HTH matrix perfect diagonal. So we come to know that we can estimate the unknown parameters exactly when PRN input is used.
