摘要：A method and apparatus encode a source data stream via convolutionalencoding. One or more encoded data streams are interleaved and transmitted on one ormore transmission channels. Data groups generated via convolutional encoding areinterleaved via time-interleaving functions to disperse selected bits within puncturegroups of the data groups, bits in between data groups, and bits in selected sets of datagroups to facilitate reconstruction of the source data stream from at least a portion ofthe interleaved data stream received on at least one transmission channel. The time-interleaving functions are selected to facilitate reconstruction of the source data streamfrom one transmission channel following continuous blockage. Subsets of bits ofpuncture groups are selected to allow reconstruction of the source data stream fromthe transmission channels using a minimum number of subsets. Multiple combinations ofsubsets can be received via two or more transmission channels to reconstruct the sourcedata stream following blockage of one channel. Decoding is performed via a Viterbidecoder.
