An improved algorithm for fast bit synchronization based on π/4-DQPSK in underwater acoustic communication

摘要：

This paper draws on a bit synchronization algorithM used for terrestrial wireless communications n/4DQPSK modulation mode and shapes the algorithm based on the characteristics of the Doppler effect of underwater acoustic channel. Simulation results show that the improved algorithm is more robust against the Doppler effect of underwater acoustic channel while maintaining the good performance of the original algorithm.
