摘要
普通的电话线路也可传输高速数字信号,为了判断普通电话传输线路的可靠性,需要测试线路误码率。利用m序列的性质,以FPGA、单片机与Modem芯片为硬件平台,实现了电话线路误码测试的应用研究。研究结果表明:该误码测试设计方法工作稳定可靠,能够实现电话线路数据传输可靠性检测。
Ordinary telephone lines can also transmit high speed digital signals. In order to test the characteristics of the telephone line, BER （Bit Error Rate） test is one of the most important aspects. The multi-frequency BER test is achieved by using FPGA （Field Programmable Gate Array）, MCU （Micro Controller Unit） and Modem chip as well as the properties of m sequence. The results show that this method is stable and reliable, which can accomplish the test of telephone lines.
