METHOD AND A DEVICE FOR CHECKING CYCLIC REDUNDANCY IN A COMMUNICATION SYSTEM, CAPABLE OF IMPROVING A DATA PROCESS RATIO BY REDUCING A DELAY TIME DUE TO CODING AND DECODING OF THE CYCLIC REDUNDANCY CHECK

摘要

PURPOSE: A method and a device for checking cyclic redundancy in a communication system are provided to reduce a delay time due to CRC coding and decoding by dividing an input signal into N segments.;CONSTITUTION: The power of x is multiplied with each sub message(501,503,505,507). The CRC decoding is performed by adding 0 to the multiplied result(511,513,515). The generated CRC is added to a GF adder. The same result as the CRC about the information message to be transmitted is obtained. The transmission information message is separated into M sub messages. Each CRC of the separated sub messages is obtained. The CRC of the information message to be transmitted is obtained by adding the CRC.;COPYRIGHT KIPO 2010
