循环冗余校验算法的实现

广东东软学院本科毕业设计（论文）ABSTRACTThis paper introduces the principle of cyclic redundancy check(CRC)algorithm and the design and analysis process of CRC algorithm,andgives the detailed process and code of coding and decoding calculation.This paper describes the specific implementation process of cyclicredundancy checking algorithm based on array simulation data package,and gives the detailed design process.This method is very fast inchecking speed,which improves the speed of computer networkcommunication and the accuracy of message transmission.Afterexplaining the design ideas,this paper will use java language to realizethe design and design,and explain the design principles and specificcontent.The coding and decoding methods of cyclic redundancy checkare relatively simple,the ability of checking errors is very strong,and theprobability of failing to check errors is basically 0.The function of errorcontrol is widely used in the field of communication,which is used todetect the data frame of various fieldbus protocols in communicationsystem.Key words:CRC test;Generating polynomials;Module 2 division:JAVA
