Dirty Paper Coding: Peturbing Off the Infinite Dimensional Lattice Limit

Motivated by its potential role in providing more efficient downlink signalling, we focus here on so called Dirty Paper Coding (DPC). DPC can immunize a link against interference when the erstwhile interferer is launched from the same transmit site. This promotes reuse of space/spectral communication resources even at the same base station since would be intererers can be made phantoms (invisible interference) to communicators on the same resource.
