Abstract


With the penetration of wireless communication technology, spectrum resources have been employed more widely. The scarceness of spectrum hampers the sustaining development of wireless communication. By sensing the spectrum environment and adjusting the transmission parameters in real time, cognitive radio can use the licensed spectrum in an opportunistic way, which will solve the problem of lacking wireless spectrum and makes itself a hot topic in wireless communication in recent years.Based on the basic theory of cognitive radio, this paper proposes a cognitive radio communication system which is composed of a spectrum environment simulator, several cognitive nodes and an administrator. Through the design of the system’s working circumstance, the functional capability of each entity, and the information transmitted between nodes as well as its frame format, a complete communication protocol is introduced. And implement the cognitive wireless communication system on hardware-based DSP+FPGA .Finally this paper introduces an improved algorithm of spectrum resource management, and verify the improvement compare to the traditional spectrum management by simulation. Aiming at improving the spectrum utilization efficiency via employing the cognitive radio technology into practical communication, the communication system in this paper can make better use of the spectrum resources with some tolerable loss of communication efficiency.
