This paper studies the clock acquisition algorithm for timing recovery for wavelet-based multirate system based on the characteristics of correlation of wavelet function and scaling function.we proposed two kinds of clock acquisition algorithm by using a new improved S-curve.These algorithms utilize redundancy of wavelet transform to locate the peak points of the correlative function and then estimate the symbols clocks.In AWGN channel,Simulation results show that the approach successfully acquires the correct timing point,but the algorithm based on wavelet function converged faster,and the algorithm based on scaling function behaved more stable.
