Beyond Cognitive Radio in Wireless Feed-back Control Systems

将其应用于反馈控制的无线电通信系统中，证明了超越认知无线电是可以实现的，它不仅可以理解无线电信道的物理环境，还可以理解应用的语义环境。提出了一种载波感知多址（CSMA）方案，该方案对数据包的重要性进行估计，并根据估计的重要性确定的数据包优先级来控制回退时间。在多个无线系统控制旋转倒立摆的情况下，通过计算机仿真对该方案的性能进行了评价。

Limiting the application in a radio communication system within feedback control, it was shown that beyond cognitive radio is realizable, which can understand not only the physical environment of the radio channel but also the semantic environment of the application. A carrier sense multiple access (CSMA) scheme was proposed, which estimates the importance of packet and controls the back-off time according the priority of the packet determined by the estimated importance. The performance of the proposed CSMA scheme was evaluated by computer simulation, assuming a situation where there were several wireless systems controlling rotational inverted pendulums.
