为了在分布式的无线网络，预兆的力量和率控制计划减轻循环延期，为系统模型被建议也说明拥挤层次和输入延期而不是在一个网络推迟状态。有输入延期的一个测量反馈控制问题被最小化之间的差别的精力提出实际并且控制的需要的 signal-to-interference-plus-noise 比率(SNR ) 层次，以及精力定序。解决这个问题，我们在场为控制的二个 Riccati 方程和在时间的评价推迟系统。一个完全的分析最佳的控制器被使用分离原则并且解决二个 Riccati 方程获得，在一个人是为随机的线性二次的规定的向后的方程，其它是标准过滤 Riccati 方程的地方。模拟结果说明建议力量和率控制计划的表演。

英文摘要：

To mitigate the loop delay in distributed wireless networks, a predictive power and rate control scheme is proposed for the system model that also accounts for the congestion levels and input delay instead of state-delayed in a network. A measurement feedback control problem with input delay is formulated by minimizing the energy of the difference between the actual and the desired signal-to-interference-plus-noise ratio （SNR） levels, as well as the energy of the control sequence. To solve this problem, we present two Riccati equations for the control and the estimation for the time delay systems. A complete analytical optimal controller is obtained by using the separation principle and solving two Riccati equations, where one is backward equation for stochastic linear quadratic regulation and the other is the standard filtering Riccati equation. Simulation results illustrate the performance of the proposed power and the rate control scheme.
