Embodiment Construction
[0033] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0034] Such as figure 1 As shown, a proportional control and normalized LMP filtering method under a CIM function, including the following steps:
[0035] S1. The input signal x(n) of the adaptive filter=[x(n),x(n-1),...,x(n-M+1)] T Optimal weight vector with filter expectation Multiply, plus the noise signal v(n), to get the desired output signal d(n):
[0036] d(n)=w o T x(n)+v(n);
[0037] In the formula, M represents the channel length;
[0038] S2. The input signal x(n) of the adaptive filter=[x(n),x(n-1),...,x(n-M+1)] T And filter real-time weight vector w(n)=[w 1 (n),w 2 (n),...,w M (n)] T Multiply to get the real-time output signal y(n):
[0039] y(n)=w(n) T x(n);
[0040] S3. Make a difference between the expected ou...
