Abstract

A BPSK carrier phase recovery algorithm is proposed that combines discrete Fourier transform with digital phase locked loop. For coarse frequency estimation, the algorithm adopts square algorithm and DFT to BPSK signal, and then initializes the DPLL frequency by the coarse frequency estimation, which satisfies that DPLL begins at pull-in range. The DPLL locks in through about one period and supplies the carrier signal to the modulation accurately. Simulation results show that the algorithm qualifies the fast and accurate synchronization, and avoids the shortage of longer time to lock that was needed by using traditional automatic frequency controller and PLL algorithm. Meanwhile, the proposed algorithm is easy for DSP chips to realize all digital structure.
