摘要
基于迟早门同步技术原理,借用MATLAB的SIMULINK系统仿真环境,建立了基于迟早门同步技术的通信系统模型,对信号生成、传输、解调和同步各环节分别进行了仿真,结果表明该同步方法具有自检同步、低误码率传输等优点。
According to early-later gate synchronous technique principle, using the MATLAB emulation environment, this paper established the communication system based on early-late gate synchronous technique, simulated the generation and modulation of digit signal , the transmission of digit signal in the channel, the synchronization. The results indicate that there are lots of virtues to use this method, such as autotest synchronization, low error-rate and so on.
