Codes for writing on dirty paper

Abstract. We have investigated coding methods that aim at achieving the Costa capacity. First we have considered the uncoded case to determine what can be gained from coding. After that we have designed codes with a trellis structure that are combined with a two-level quantizer at the transmitter side. Simulations are carried out to determine the coding gains of these methods. We have focussed on vector quantization instead of on scalar quantization to achieve a good performance. 1 System description w x ✓❄ ✲ encoder ✲ + ✲ + ✲ decoder
