| 摘 要： | 介绍了无线MIMO系统信道容量的计算方法,重点分析和比较了在瑞利衰落信道下,发射端已知或未知,但接收端完全未知的信道状态信息时的独立同分布的多入多出各态历经容量特性。并利用Matlab对其进行仿真。结果表明,在低信噪比时,采用自适应功率分配得到的信道容量特性要优于采用平均功率分配。并且信道容量随收、发天线数目的最小值呈线性增长。

| Abstract: | This paper introduces the computing method of channel capacity in MIMO Wireless Channel.It mainly analyzes and compares the ergodic capacity of independent and identically distributed(i.i.d.) multiple-input multiple-output(MIMO) Rayleigh flat fading channels when channel state information(CSI) is unknown and known to the transmitter but perfectly known at receiver.Moreover,a computer simulation with Matlab is implemented.The simulation result indicate that performance of channel capacity with the optimal po... |
