The Detection Method of Doppler Frequency Offset Based on Chaotic Dual Oscillator for MSK Signals

Phase-locked loop and other traditional synchronization program does not apply to MSK signal in low SNR condition. Aiming at this problem, a nonlinear chaotic frequency detection scheme is proposed to realize the accurate detection of the weak MSK signal's Doppler frequency offset. Firstly, the principle of frequency detection using chaotic oscillator is… CONTINUE READING
