Abstract:
1. A communication system managing an available spectrum resource and accessing to a backbone network, comprising: a cloud having a spectrum resource management unit and a radio access management unit; and a wireless communication network connected to the cloud, and having a plurality of cognitive radio access points and a plurality of users, wherein the spectrum resource management unit accesses a database and distributes the available spectrum resource to the plurality of cognitive radio access points, the radio access management unit coordinates the plurality of cognitive radio access points and the plurality of users, and the cloud coordinates the plurality of cognitive radio access points to process channel requests received from the plurality of users, and uses the results fed back from the plurality of cognitive radio access points and a realtime channel and power allocation (CPA) mechanism to control the signal to interference-plus-noise ratios (SINR) for each user of the communication system.
