Abstract

An initial data stream is coded using a first set of n coders to form n coded data streams, which are subsequently punctured by combining the n coded data streams with a first puncturing data field to form a first punctured data stream. The initial data stream is also interleaved using k interleaving circuits to produce k interleaved data streams, which are subsequently coded using a set of m coders to form m coded interleaved data streams. In addition, a second puncturing data field is interleaved to form an interleaved puncturing data field. The m coded interleaved data streams are subsequently punctured by combining the m coded interleaved data streams with the interleaved puncturing data field to form a second punctured data stream. The initial data stream, the first punctured data stream and the second punctured data stream are multiplexed to form a transmission data stream.
