Abstract

Cognitive radio are always based on spectrum sensing to cognize the physical characteristics of the wireless channel and carry out wireless communication resource scheduling. This kind of method has limited predictive ability and cognitive content, which cause it is hard for cognitive radio to response to the change of radio environment in advance. This paper proposes a new system called visual cognitive radio, which use visual information to cognize radio environment. Visual observation has well predictive ability and abundant cognitive information, which enables the visual cognitive radio to deal with the change of radio environment in advance and make optimal configuration to the process of wireless communication. This paper presents a typical communication scene as an example to explain the advantage of visual cognitive radio, and also makes a preliminary analysis of the application and challenge of visual cognitive radio.
