Abstract :
The dirty paper coding (DPC) can achieve rate region for multicell cooperation system. In this paper, the joint GMDTHP based DPC transmission scheme with user selection for multicell processing is proposed, and the channel condition number based distributed user scheduling algorithm with low complexity is presented. Simulation results shown that the BER performance of the proposed scheme is better than the conventional ZF DPC, and it is more suitable for the multicell communication system.
