摘要
数字通信系统具有抗噪声性能好,传输质量高,便于保密等一系列优点而得到迅速的发展。数字通信系统有基带传输和频带传输两种传输方式。基带数字信号的传输在有线通信系统中得到了广泛的应用,在无线通信系统中也有一定的作用,有必要对基带数字传输中产生的误码进行分析。
The digital communication systems have advantages of good noise resistance,high-quality transmission and easy secrecy-maintaining.Therefore they develop fast.The systems have two ways of transmission:base band transmission and band transmission.The former finds wide application in the cable communication system and plays a cartain role in the wireless communication system.The paper analyses the error codes caused by the base band transmission.
