In the process of data transmission,the most important is data synchronous transmission,it needs insert frame synchronizing word in the data and testing it with digial correlation device in the process of data transmission.
在数字通信的数据传输过程中,需要保持数据在传输过程中的同步,因此要在数据传输过程中插入帧同步字并用数字相关器对帧同步字进行检测,从而有效地避免发送数据与接收数据在传输过程中出现的异步问题。
