摘要
本文简要叙述CRC方式在PCM基群复用设备中的应用。并对循环码的编码方法、帧内第1比特的具体描述、CRC的帧定位以及利用比特误码监测等进行了论述。最后梗概介绍了CRC—4的具体实现方案和计算机模拟的结果。
This paper gives a brief description for the application of CRC in the primary PCM multiplexing equipment. Discussions are focused on the coding method of cyclic code, the concret situation of CRC in the first bit of a frame, the frame location of CRC and the monitoring of bit-error and mode. In the end, the detailed realizable scheme for CRC-4 and the results of the computer simulation are briefly demonstrated.
