Implementation of Error Control Based on Cyclic Redundancy Check

In high-speed digital communication networks,due to noise interference,instantaneous disconnection and other kinds of reasons,the signal inevitably produces errors during transmission.In order to ensure the reliability of the data during transmission,so an error control strategy was introduced to check and correct the errors during the course of transmission.CRC(cyclic redundancy check) is widely used as error-correction coding in recent.A Go-Back-N error control strategy based on the cyclical redundancy check was analyzed and a reliable means to achieve cyclic redundancy check with hardware and software was proposed respectively.
