本文考虑了无线状态反馈控制的通信层和控制层的跨层设计，并提出了一种优化的接收器。所提出的接收器是基于最大后验概率（MAP）的接收器，其利用基于卡尔曼滤波器的状态观察器的估计状态信息作为传输状态反馈的先验知识。它利用了反馈控制环路的递归结构。仿真结果表明，所提出的接收机能够有效抑制信道误差，提高控制性能。
This paper considers a cross-layer design of communication and control layers for wireless state feedback control, and an optimized receiver is proposed. The proposed receiver is a maximum a posteriori probability (MAP)-based receiver that utilizes estimated state information of a Kalman filter-based state observer as a priori knowledge of transmitted state feedback. It takes advantages of the recursive structure of feedback control loop. Simulation results show that the proposed receiver can effectively suppress channel errors and improve the control performance.
