无线通信网络建模及功率和速率控制

摘要
现有的无线通信网络功率和速率控制方法没有考虑时变时滞和非线性信道衰落。建立了一种新的基于信噪比的考虑时变时滞和非线性信道衰落的无线通信网络功率和速率控制的系统模型,并针对此模型给出了鲁棒功率和速率控制方法。该方法充分考虑了由于未建模动态和外部干扰引起的不确定性,基于线性矩阵不等式设计了鲁棒功率和速率控制器,并且通过线性矩阵不等式进行分析。仿真结果表明了给出控制器的有效性。
A new system model based on signal to noise ratio for power and rate control of wireless communication networks with time-varying delay and nonlinear channel fading is established. And the robust power and rate control method is given based on this model. The method takes full account of the uncertainty caused by external disturbances. A robust power and rate controller is designed and the analysis is carried out by linear matrix inequalities. Simulation results illustrate the effectiveness of the proposed controller.
