Abstract :
The vector dirty paper coding (DPC) can achieve rate region for multicell cooperation system. Conventional DPC implementation approach suffer the capacity loss due to quantization which lead to modulo loss. In this paper, we proposed a vector DPC transmission scheme with non-binary LDPC codes and low density generator matrix based quantizer for multicell processing. And the random coding based proof for the encoding and decoding transmission system is presented. It can achieve a shaping gain and significantly reduce computational complexity.
