本文介绍一种利用时分复用设备中的群同步信号进行传输误码实时测量的方法,从而实现了在数字通信中传输各种数据、电报、传真等数字信号的同时进行传输误码率的测量。文中给出了实现方法及试验数据,并与常规的传输误码率测量数值进行了比较。
In this paper, a method for real-time measurement of transmission errors using group synchronization signals in time-division multiplexing equipment is introduced, so as to realize the measurement of transmission bit error rate while transmitting various digital signals such as data, telegraph and fax . The implementation method and experimental data are given in this paper, and compared with the conventional transmission BER measurement.
