CA 2475863

A device and method for matching a rate of 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 convolution code or a linear function code) and a systematic code (such as a turbo code). The rate matching device includes a plurality of rate matching functions, the number of the rate matching functions 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/repetition parameters determining parameter.
