Zero-forcing based coordinated multi-point transmission systems and power allocation
基于迫零传输的协作多点传输系统的功率分配*

On the basis of the multiple base stations systems,this paper proposed the system model of coordinated multi-point transmission systems, and used zero-forcing transmission mechanism, comparative analysis the optimal power allocation, the optimization power allocation, the equal power allocation. At last,considering the performance and complexity, come to the optimization power allocation is a kind of compromise of power allocations.
