Abstract :
A frequency synchronization algorithm utilizing the peak phase error detection and frequency offset smoother is proposed for burst data transmission. The basic idea of frequency offset estimator (FOE) is to use a curve fitting method. The proposed peak phase error detection avoids a large phase error giving a bad value for FOE. For the purpose of controlling the automatic frequency control (AFC), frequency offset smoother by a simple filter is used. Simulation results show that the proposed algorithm is adequate for frequency synchronization of burst data transmission.
