APPARATUS AND METHOD FOR TRANSMITTING/RECEIVING DATA IN A COMMUNICATION SYSTEM

摘要

PURPOSE: A data transceiver in a communications system is provided to enhance the quality of a broadcasting system by generating an additional parity bit string to obtain sufficient diversity gain. CONSTITUTION: An encoding unit (510) encodes information bits, which are inputted for transmission, using a given encoding technique and an encoding rate. A parity reconfiguring unit (520) produces a basic parity bit string and at least one additional parity bit string from a parity bit string which is provided by the encoding unit. The parity reconfiguring unit includes a basic parity generator (522) which produces a basic parity bit string and additional parity generator (524) which produces an addition parity bit string. A frame generating unit (530) produces frames to be transmitted based on a systematic bit string which is provided by the encoding unit, and a basic parity bit string and an additional parity bit string which are provided by the parity reconfiguring unit.
