Abstract
The experiment simulates a complex signal with several frequencies and the Rayleigh noise signal. We use a bandpass filter based on wavelet packet to analyze the signal. In the frequency domain, the results show that the method can separate any frequency signal from the original signal. In the time domain, the method can reconstruct the original signal correctly when the SNR is high, but when the SNR is low, the method can´t reconstruct it effectively.
