PURPOSE: An apparatus and a method for coding block data are provided, which codes important block data with short length efficiently, and can realize a simple system by reducing the number of required channel encoders. CONSTITUTION: A mixer(301) mixes a plurality of block data(A block, B block) regularly, and a channel encoder(302) codes one block data mixed by passing through the above mixer. And a non-equidistant puncturer(303) applies different error protection level respectively as to each sub block in the output block data of the channel encoder. Instead of using two channel encoders, the non-equidistant puncturer is used to apply different error protection level each other according to the importance of each sub block, and thus the number of channel encoders is reduced, and it is possible to realize a simple communication system.
