摘要：

Acute change of BPSK signal amplitude seriously affects the PLL's bandwidth and stability. A high stable synchronization algorithm for BPSK carrier phase is presented in this article that unifies the techniques of digital automatic gain controller (DAGC) and DPLL. The non-coherent DAGC, which adopts an exponential gain controlled amplifier, adjusts the modulated signal amplitude to the settled value, and then the amplitude-stable signal input to the third order DPLL to recovery accurate carrier phase. Simulation results confirm that the presented algorithm could prevent the instability of third order DPLL from the change of signal amplitude. It also satisfies the requirements of BPSK demodulation performance when the signal is within the intended SNR range.
