Abstract: A device and method for rate matching channel-encoded symbols in a data communication system. The rate matching device and method can be applied to a data communication system which uses one or both of a non-systematic code (such as a convolutional code or a linear block code) and a systematic code (such as a turbo code). In one aspect, the rate matching device includes a plurality of rate matching blocks, the number of the rate matching blocks being equal to a reciprocal of a coding rate of a channel encoder. The rate matching device can rate match the symbols encoded with a non-systematic code or the symbols encoded with a systematic code, by changing initial parameters including the number of input symbols, the number of output symbols, and the puncturing or repetition pattern determining parameters.
