METHOD AND A DEVICE FOR ALLOCATING AN IMPLEMENTATION FRIENDLY RESOURCE COUPLED WITH ADMISSION CONTROL IN AN OFMDA WIRELESS COGNITIVE NETWORK, CAPABLE OF MAXIMIZING EFFICIENCY OF USING A FREQUENCY

摘要

PURPOSE: A method and a device for allocating an implementation friendly resource coupled with admission control in an OFDMA(Orthogonal Frequency Division Multiple Access) wireless cognitive network are provided to control concentration interference, thereby protecting a main system.;CONSTITUTION: Initial channel scheduling and power allocation are performed about each sub transmission node(201). It is confirmed that a channel of a main system is used(202). When the main system operates in a corresponding channel and an adjacent channel, simultaneous scheduling of nodes is confirmed(203). It is confirmed that α and β values optimized for a given network environment exist(204). A proposed algorithm is driven at a tuning mode(205). The proposed algorithm is driven at a blind mode(206).;COPYRIGHT KIPO 2011
