| Abstract: | A novel method of weak signal reception based on wavelet transformation is proposed.Denoising procedure of the unsmoothed signal is simulated in condition of the low signalnoise ratio, and it is compared with the way of Fourier transformation. It is proved that this method can solve the problem of weak signal reception effectively. |
