| Popis: | This paper simulates and models the PCM-FM signal under multipath effect, and compares the changes of the original signal and the multipath synthesis signal in the time domain and the frequency domain. The analysis results show that the multipath interference causes the PCM-FM signal. In the time domain, the amplitude of the waveform is severely fluctuated, and the spectrum in the frequency domain is distorted. Therefore, the CMA-based PCM-FM signal multipath interference blind equalization algorithm is studied and verified by simulation. The simulation results show the amplitude of the multipath synthesis signal. The equalization effect is obvious, which can effectively reduce the influence of multipath interference on the PCM-FM signal. |
