APPARATUS AND METHOD FOR INTERLEAVING IN COMMUNICATION SYSTEM

摘要

An apparatus and a method for interleaving in a communication system are provided to reduce complexity of hardware by regulating a read address generation period. A method for interleaving in a communication system includes the steps of: deciding an 'm' and a 'j' based on a size of encoding packet(401); initializing an 'I' index and a 'k' index as '0'(403); generating a read address, 'Ai' using the 'k' index(405); determining whether the 'I' index is equal to N-1 or not(407); completing algorithm, if the 'I' index is equal to the N-1; determining the 'k' index is satisfied with a specific rule, if the 'I' index is not equal to the N-1(409); increasing 1 in the 'k' and 'I' indexes and going to the 405 step for generating the next read address, if the 'k' index is valid(413); and increasing 2 in the 'k' index for skipping next 'k' index and increasing 1 in 'I' index and going to the 405 step for generating next read address, if the next 'k' index is to be expired(411).
