Analysis and design of dirty paper coding

Abstract

In this thesis, we consider the analysis and design methods of Dirty Paper Coding (DPC). DPC is one of the interference pre-cancelation schemes, which was developed by Costa. DPC has known the capacity achieving scheme in Gaussian vector broadcast channel. Therefore, its practical implementations are important for a system to obtain maximum throughput. We show the background of DPC, and its analysis. In general, DPC uses two independent channel codes, one is error correction code, the other is shaping codes. Through choosing the simplest shaping code such as repetition code, we can obtain the capacity of the channel plus shaping code. We design DPC implementation to approach this capacity. We also design other DPC implementation, that is, turbo DPC. It has similar structure with turbo code which has used widely in real communication system. Therefore, it helps the implementation of DPC with a few modification of the system.
