Abstract :
The IS-856 system delivers high spectral efficiency on the forward link by using dynamic link adaptation, hybrid ARQ and multi-user diversity scheduling. The channel coding/modulation scheme used on the forward link is designed to support incremental redundancy for hybrid ARQ, while maximizing the coding gain over static channels. This paper presents the design of the channel-coding scheme used on the IS-856 forward link. It highlights a "novel" interleaver design that provides near-optimal code puncturing and modulation symbol mapping, in addition to randomizing burst errors on the channel.
