Carrier Frequency Blind Estimation of MC-MPSK Signal Using Wavelet Transform

Methods of wavelet transform are effective methods of time-frequency analysis under the background of strong noise.A method to estimate the frequency of multi-carrier m-ary phase-shift keying(MC-PSK) signals is showed,it uses Haar's wavelet transform.Simulation is used.The algorithm is compared to modified carmer-rao bound(MCRB),it shows that the methods of wavelet transform can accurately estimate the carrier frequency of MC-PSK signals without prior knowledge.The estimation performance is effected by phase noise very slightly.
