Research Of The Database That Supports Dynamic Spectrum Management And Simulation Software

Using spectrum resource reasonably and fully always becomes very important because spectrum resource is scarce。Cognitive Radio,a new technology that recycling the spectrum resource which has been assigned to someone but sometimes is vacant,improves the spectrum utilization。Through the extension of Cognitive Radio,we put forward"Dynamic spectrum management method"to improve the spectrum utilization。This system is the complement and modifications to the traditional frequency management rule,and it contains measures that how to distribute the frequency and protocol that how to supervise the unauthorized users。This thesis introduces a database supporting Dynamic spectrum management as well as data processing and query method。The software that imitates this management system carries out various shows of processes and evaluations of performances。All these make Dynamic spectrum management convenient and make the management and assignment quick and exact。...
