Rate matching device and rate matching method

摘要

A data distributor distributes interleaved data strings and outputs them to puncturing sections in a frame unit. A puncturing instructing section refers to a rate matching table to output information on data to be punctured to a plurality of puncturing sections. Each puncturing section performs the judgment processing on whether puncturing is to be performed only for parity bits according to the rule of an arrangement of information bits and parity bits for each frame and then performs puncturing. This enables to reduce processing for turbo-coded data after interleave processing and to perform light-load rate matching.
