摘要 有效的功率控制方法在蜂窝无线通信系统的设计中非常重要。该文提出了MIMO蜂窝系统中的功率平衡方法,并对此方法进行了性能仿真。结果表明,在接收天线数目多于发射天线数目的情况下,该文提出的功率平衡方法可以有效降低多天线系统接收端的BER值。 Efficient power control is very important in the design of cellular radio systems. In this paper, a power balancing method is proposed in Multi-Input Multi-Output (MIMO) cellular systems,and BER performance is analysed. Simulation results indicate that power balancing can decrease BER at receiver when the number of receiver antennas is greater than that of transmitter.
