CHANNEL CODING DEVICE AND METHOD FOR RATE MATCHING

摘要

A bit inserter (702) inserts known bits at predefined positions in the input data bit stream. A channel coder (703) codes the bit inserted data stream to generate coded symbols. A rate matcher (704) matches the rate of coded symbols to a given channel symbol rate. A channel interleaver (705) interleaves the rate matched channel symbols. The rate matcher comprises a puncturer which punctures inserted known bits included in the coded symbols when coded symbol rate is higher than channel symbol rate. The puncturer punctures only specific parity symbols among that output by channel coder. An independent claim is also included for channel coding method.
