数字通信系统中一种新型差错控制方案

对当今主流数字通信系统中的差错控制技术进行了分析，并针对其不足提出了一种 新型差错控制方案。利用两条信道同时传输数字信息，传送的信息相位相反，信息中无监督 码元，在接收端利用差分技术对这两个信号进行处理。分析表明，该方案在信号的传信率、 误码率和编码效率指标上优于传统差错控制技术，且实现更为简单。

A Novel Error Control Scheme for Digital Communication Systems

The error control methods applied in digital communication systems are analysed, and on this base,a novel solution of error control is proposed. Digital information is transmitted through two channels simultaneously. The phas es of two signals are reversed and there is no check code in the signal. These two signals are process ed at the receiving end by using differential technique. Analysis results show that this solution is superior to previous ones in transmission rate, error rate and code rate, and is simpler for implementation.
