Throughput analysis:
COGNITIVE radio technology has recently emerged as an aspirant solution for the problem of spectrum scarcity.Unlike the traditional static command-and-control approach, it provides a more dynamic means for spectrum management and utilization channel state information (CSI) is one of the main requisites
for successful implementation of such dynamic cognitive radio protocols. However, its availability is often sidelined in most previous works either assuming a centralized band manager or perfect instantaneous CSI feedback between primary and secondary networks
Fig:Throughput analysis of Cognitive radio
the design of optimum distributed power control mechanisms for the cognitive uplink,allowing each SU to adjust its transmission power level based only on local knowledge of its CSI. It also investigates multiuser diversity gains for the distributed cognitive uplink by deriving tight sum-rate capacity scaling laws under the optimum distributed power control mechanisms.
