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.

Famous quotes containing the words dirty and/or paper:
“Politics is still the man’s game. The women are allowed to do the chores, the dirty work, and now and then—but only occasionally—one is present at some secret conference or other. But it’s not the rule. They can go out and get the vote, if they can and will; they can collect money, they can be grateful for being permitted to work. But that is all.”
—Mary Roberts Rinehart (1876–1958)
“It was because of me. Rumors reached Inman that I had made a deal with Bob Dole whereby Dole would fill a paper sack full of doggie poo, set it on fire, put it on Inman’s porch, ring the doorbell, and then we would hide in the bushes and giggle when Inman came to stamp out the fire. I am not proud of this. But this is what we do in journalism.”
—Roger Simon, U.S. syndicated columnist. Quoted in Newsweek, p. 15 (January 31, 1990)
