| Abstract: | In this paper a new signal estimating method-wavelet transformation is given. It's also proved by theoretical and emulation that spectrum estimation based on wavelet transformation has better distinguishing rate than that of FFT. It also discussed the algorithm of spectrum estimating,the dual-sine emulative result is given at last. |
