Wavelet Transfer (WT) is a powerful technique in signal separation. It is very easy for WT to improve the signal-to-noise (SNR) by separating the random noise and useful signal.
小波变换技术具有很强的信号分离能力容易把随机噪声从信号中分离出来,从而提高信号的信噪比。

The interval of the time lag is identical of each lane controlled and when the input is a random sign, we can adopt quadratic function of optimum control and separation theorem.
