In this thesis, a new efficient timing recovery algorithm for continous phase modulation(CPM) is proposed. This algorithm estimates the timing error using phase error which is mapping to timing error. The proposed algorithm uses the differential terms of trasmitted signal to eliminate initial phase offset and signal sampled at nT+T/2 to avoid phase ambiguity. The proposed algorithm works in digital domain. Using simulations for CPM(MSK,3REC,3RC) signals in AWGN channel, the performance of the proposed algorithm is evaluated in terms of steady-state timing error variance and convergence time. Computer simulations verify the effectiveness and generality of this proposed synchronizer. The porposed algorithm shows nearly the same performance as conventional timing recovery algorithm for CPM in full response signaling. While the conventional timing recovery algorithm fails in partial response signaling, this proposed algorithm works succesively. And the proposed algorithm is efficient in hardware complexity.
