Abstract:
1. A method for generating a standard cancellation signal, comprising: setting weight values according to frequency points of a current cell and its neighboring cells; performing a fast Fourier transform to obtain a corresponding time-domain signal according to the frequency points of the current cell and neighboring cells and the weight values of the frequency points; and performing highest amplitude normalization on the time-domain signal and performing a cyclic shift to obtain a standard cancellation signal; wherein the performing the fast Fourier transform comprises: determining a point number of the fast Fourier transform according to frequency points that participate in suppression on a network, wherein the point number is n=2 adjusting the point number according to the weight values, and using the point number that has undergone the adjustment to the fast Fourier transform to obtain a time-domain signal {right arrow over (x)}=[x where i indicates an index of a time-domain signal sampling point, i=0, 1, . . . , n−1, k indicates an index of a frequency-domain subcarrier, k=0, 1, . . . , n−1, and j=√{square root over (−1)}.
