pulse synchronization

With the LFM pulse frame synchronization method, the performance of UWA communication system based on DPSK is apparently improved.

同时运用线性调频脉冲帧同步法，改善了基于差分相移键控的水声数字通信系统的性能。

In order to improve the synchronization in signal demodulation, we modify the traditional modem scheme by adding a '1' bit as synchronization pulse to the beginning of each byte. The modified modem scheme avoids bit errors caused by desynchronizing.

为了改善信号解调中的同步问题，论文对传统调制解调技术进行了改进，通过为每个字节添加一个1比特作为该字节的同步脉冲，消除了因不同步而导致的误码。
