| 摘 要： | 为保证数据传输的正确性,需要对通信过程进行差错控制。循环冗余校验CRC由于编码简单、误判概率低,在测控通信系统中得到了广泛的应用。介绍了循环冗余校验码的基本原理,重点分析了其硬件电路的实现方法,并在此基础上用VHDL语言设计了编码程序,给出了应用于测控通信系统中的仿真结果。

| Abstract: | In order to ensure the correct data transfer, the error control algorithm is adopted. For its simple coding and low rate of error identification, the Cyclic Redundancy Check is widely used in digital communication system. The paper gives the principle of CRC and provides the hardware implementation based on VHDL. The author presents the program and the simulation result of its application in communication system. |
