Nakagami信道的中断容量分析

Analysis of outage capacity in Nakagami fading channels

本文讨论了Nakagami-m衰落信道系统的中断容量性能,在发射端未知信道信息,接收端的信道估计存在误差时,给出了计算中断容量上界和下界的表达式,它们是接收端的估计误差和信道参数的函数,仿真结果表明随着估计误差的增大中断容量的上界和下界同时降低,但是中断容量的下界随着信道参数的增大而增大,上界随着信道参数的增大而减小。

The outage capacity in Nakagami-m fading channel with no channel state information （CSI） at the transmitter and partial CSI at the receiver is considered in this paper. Analytic expressions for the upper and lower bounds of the outage capacity are obtained as a function of the channel estimation error at the receiver and the channel parameter. Simulation results show that the increment of channel estimation error decreases the upper and lower bounds of outage capacity. But the channel parameter has different effect on upper and lower bounds of outage capacity.
