Abstract

For high-speed digital receivers, the crucial problem is to find a parallel carrier synchronization algorithm, but the traditional carrier synchronization methods based on phase-locked loop (PLL) are difficult to be parallel implemented. In this paper, we propose a parallelizable carrier synchronization algorithm based on maximum likelihood estimation (MLE). The simulation results show that the performances of locking and without losing are very good when proper data length for estimation is selected. Finally, the algorithm is applied to practical communication systems and the results show that the device utilization and BER performance loss are all very low.
