New time-frequency method of harmonic signal extraction in chaotic secure communication system
after the time-frequency character analyses of the chaos,the noise and the harmonic signal,a new two-step extraction method of time-frequency was put forward,aimed to complement each other’s advantages and mutual fusion for wavelet multi-scale decomposition and empirical mode decomposition.The probl...
