%X Carrier synchronization is one of the most important parts in communications. This paper makes analysis on PLL’s phase error during EBPSK carrier recovery. Firstly, under the narrow band Gauss noise condition, PLL linear model is established and output phase noise variance is figured out. Then, comparisons are made with the squiring loop and Costas loop of BPSK. Some simulations are carried out with different input SNR and loop Bandwidth. The results demonstrate that EPBSK signal with duty ratio of 1:9, phase shift of π/4, and SNR lower than 6dB performs better than BPSK in carrier recovery.
