| Abstract: | The Communication goal is must timely and reliably transmit information to the other side.Thus requiring a communication system to be reliable and fast information transmission.In a digital communication system,reliable and rapid is often contradictory.To solve the reliability of communica-tions systems,It is used error control coding.This paper describes a CRC(Cyclic Redundancy Check) Principle and error control algorithm.The CRC-4 as an example,the CRC code are given specific cal-culations and the use of VHDL coding circuit to achieve CRC,and used Altera Corporation EDA tools Quartus II as a compiler,simulation platform,selected Cyclone series of devices,completed the CRC-4 encoder circuit design. |
