EspañolDIRTY PAPER CODING (DPC)
'Dirty paper coding (DPC)' is a coding technique that pre-cancels a known interference where the known interference is a interference known at the transmitter before self-data transmission. DPC achieves the link capacity without power penalty as much as a capacity with no interference regardless of interference state information knowledage at the receiver. Examples of Dirty paper coding includes Costa precoding [1], Tomlinson-Harashima precoding[2][3] and the vector perturbation technique[4].
Note that DPC at the encoder is an information theoretic dual of Wyner-Ziv coding at the decoder.
Recently, DPC is widely researched as a solution to optimize the future wireless networks. For example, it is essential to apply the DPC concept into a precoding technique for multiuser MIMO wireless networks [5] and into an interference aware coding technique for dynamic wireless networks[5]. One important remark for the practical use of DPC is that either DPC or a DPC-like technique requires the side information such as interference status information where interference status information includes channel state information and other user data information. Hence, to design DPC-based systems we should consider the procedure to feed the side information to the transmitter(s).
Recently, DPC is also adopted in ''informed digital watermarking technics''.
