Doping of repeat-accumulate codes for dirty paper coding


Costa's “writing on dirty paper”-channel model poses one of the remaining challenges to the coding community. Theory suggests that arbitrary interference on the channel (known at the transmitter) can be cancelled without a power penalty by appropriate precoding and shaping. We employ iterative quantization and decoding using systematically doped repeat-accumulate codes to materialize a significant portion of the promised “dirty paper”-capacity. Code design is done using the EXIT chart technique.
