Abstract:
1. A method of interleaving a source data stream for transmission comprising the steps of: encoding said source data stream to generate an output data stream using a convolutional coding scheme having a selected code rate, said output data stream being characterized as a series of data groups, each of said data groups comprising a plurality of punctured data groups, each of said punctured data groups having a reduced code rate with respect to said selected code rate; interleaving said data groups in accordance with a plurality of time-interleaving functions to disperse said bits in said data groups within said output data stream and generate an interleaved data stream; and transmitting said interleaved data stream on at least one transmission channel, said time-interleaving functions being selected to disperse different groups of bits in said output data stream selected from the group consisting of said bits in one of said punctured data groups, said bits in adjacent said data groups, and said bits in selected sets of said data groups to facilitate reconstruction of said source data stream from at least a portion of said interleaved data stream received via said at least one transmission channel.
