A flexible symbol-timing synchronization method is a one that uses a common sampling clock to find synchronization points for radio communication systems that have different symbol rates This method estimates synchronization points from state patterns calculated using the symbol rate, sampling clock, and number of observed symbols Decreasing the number of state patterns is one of best ways to reduce the amount of device resources needed to store the patterns In this paper, we propose a new pattern generation method in which the number of generated patterns does not increase when the sampling clocks of the communications systems are different To show the feasibility of this method for symbol-timing synchronization, we analyzed a relationship between the number of samples and the number of state patterns and calculated the BER (bit error rate) in AWGN (additive white Gaussian noise) and one-path flat Rayleigh fading environments by computer simulation
