摘要：
The paper provides the optimal power allocation in two-tier multi-antenna cognitive femtocell radio networks. The multiple antennas are used to serve a dual objective: avoid the interference and enhance throughput via multi-input multi-output (MIMO) transmission towards the receivers. A method is presented in order to achieve the optimal power allocation for the femtocell base station (FBS). The simulation results show that the proposed method achieves good efficiency.
