Research on Blind Estimation and Synthesis of FM Speech Frequency Hopping Signal

Abstract

This paper mainly studies the blind estimation and synthesis of frequency hopping points of speech signals based on frequency modulation in the case of frequency hopping.FM voice frequency hopping signal transmitter and receiver are built based on MATLAB platform. The transmitter FM modulates the original signal and then performs frequency hopping processing; the receiver blind estimates the frequency hopping point of the received signal.
