<p>A method and apparatus for convolutionally encoding (30) and interleaving (46, 48) a source data stream for transmission on one or more transmission channels (66, 68). Convolutionally encoded data groups (36) are time-interleaved (46) to disperse selected bits of puncture groups (45) in the data groups, bits in between data groups, and bits in selected sets of data groups, facilitating reconstruction of the source data from at least a portion of the interleaved data received on at least one transmission channel. The time-interleaving functions (46) are selected to facilitate reconstruction of the source data from one transmission channel following continuous blockage. Puncture groups are selected to allow reconstruction of the source data using a minimum number of puncture group bits. Multiple combinations (44a-44d) of puncture group bits can be used to reconstruct the source data following blockage of one channel. A Viterbi decoder (26) performs decoding.</p> |
