Abstract :
We present a symbol synchronization scheme using wavelets that completely eliminates the pattern-dependent jitter. This is achieved by obtaining the optimal pre-filter using a particular linear combination of the wavelet and its translates. We further investigate synchronization schemes for the case where both the scaling function and wavelet are used simultaneously as shaping pulses for modulation, and explicit expressions for the variance of the timing jitter in the tracking mode are derived. The results are then generalized to the case where shaping pulses are produced by splitting the spectrum of a shift orthogonal function
