Abstract:
A mobile communication system, comprising:a source of digital data, for communication to or from a predetermined one of a plurality of mobile stations;a first constituent encoder, coupled to the source, for encoding the digital data into a first code sequence;an interleaver, coupled to the source, for interleaving the digital data;a second constituent encoder, coupled to the interleaver, for encoding the interleaved digital data into a second code sequence;a first code puncturer, coupled to the first and second constituent encoders, for selectively combining data from the first code sequence and data from the second code sequence according to a first puncturing pattern, to form a first punctured code sequence;a second code puncturer, coupled to the first and second constituent encoders, for selectively combining data from the second code sequence and data from the first code sequence according to a second puncturing pattern, to form a second punctured code sequence;first and second transmitters for transmission of information on first and second logical channels assigned to the predetermined mobile station; andwherein at least during a handoff operation, the first transmitter broadcasts the first channel carrying a first representation of the digital data together with the first punctured code sequence, and concurrently the second transmitter broadcasts the second channel carrying a second representation of the digital data together with the second punctured code sequence.
