Embodiment Construction
[0104] A kind of wavelet weighted multimode blind equalization method based on mixed monkey group optimization of the present invention will be further described below in conjunction with accompanying drawings and specific embodiments:
[0105] The principle block diagram of the present invention is asfigure 1 as shown, figure 1 Among them, a(k) is the complex signal transmitted by the source; c(k) is the channel impulse response vector with length L, c(k)=[c(k),L,c(k-L+1)] T ; b(k) is the additive Gaussian white noise in the communication process; y(k) is the complex signal sequence after channel transmission with length L, y(k)=[y(k+L),L,y (k-L)] T , R(k) is the complex signal of y(k) after wavelet transformation; F(k) is the weight vector of the equalizer, F(k)=[F 0 (k),L,F L (k)] T (The superscript T represents the transpose); z(k) is the output complex signal of the equalizer; the subscripts Re and Im represent the real and imaginary parts of the parameters, respectiv...
