Abstract :
In the paper a new method based on feedforward carrier estimation circuit is described for BPSK carrier synchronization. Simulation of model based on proposed method shows comparable performance with square-law and Costas loop feedback circuits in small frequency shift conditions in AWGN channel, but operates in a frequency range up to 10% of symbol rate with slowly degrading BER comparing to maximum tracking range of 3% of symbol rate for feedback circuits. Due to its wide frequency band and implementation simplicity, proposed circuit is recommended for using in the communication BPSK systems with large Doppler shift.
