In telecommunications, dirty paper coding (DPC) is a technique for efficient transmission of digital data through a channel subjected to some interference known to the transmitter. The technique consists of precoding the data in order to cancel the effect caused by the interference.
Dirty-paper Coding achieves the channel capacity, without power penalty and without requiring the receiver to gain knowledge of the interference state.
Note that DPC at the encoder is an information-theoretic dual of Wyner-Ziv coding at the decoder.
