(54)A data communication system and rate matching method


(57) A data communication system and a rate matching method to be applied in such data communication system are disclosed. It is possible to use one or both of a non-systematic code (such as a convolutional code or linear block code) and a systematic code (such as a turbo code). According to one aspect, the data communication system comprises a rate matching means with first to third rate matching means for receiving systematic bit stream, first parity bit stream, and second parity bit stream. At least one of the rate matching means rate matches a determined number of parity bits in a respective parity bit stream and a part of the encoded bits are rate matched in each of the rate matching means respectively, and can be controlled according to rate matching parameters. Corresponding bits to be rate matched among the encoded bits are controlled by a subtraction function.
