With the rapid development of communication technology, digital signal processing and other technologies, wireless communication environment is becoming more and more complex. Communication signals with different frequencies and modulated modes are usually scattered over a wide frequency band. In this paper, an improved algorithm based on wavelet transform and fractal theory is proposed. To improve the traditional fractal theory, wavelet transform is applied to the modulation signal, and thendoi:10.23940/ijpe.19.03.p29.9981004 fatcat:kgz2jpnyfzdv7jkbiyj4l23zxq
