摘要 在研究多基站系统的基础上,提出协作多点传输的系统模型,并采用迫零传输机制,对最优功率分配算法、优化的功率分配算法以及等功率分配算法进行性能比较分析。最后从性能和复杂度两方面考虑,得出优化的功率分配是一种比较折中的功率分配方法。 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.
