METHOD AND APPARATUS FOR COOPERATIVE SPECTRUM SENSING USNIG DIRECTIONAL ANTENNA IN COGNITIVE RADIO NETWORK

摘要

A cooperative spectrum sensing method using a directional antenna in a wireless cognitive network is provided. A cooperative spectrum sensing method using a directional antenna in a wireless perception network according to an embodiment of the present invention is a cooperative spectrum sensing method for detecting a main transmitter using a plurality of auxiliary transmitters equipped with a directional antenna in a wireless perception network, Receiving sensing information as a result of sensing the main transmitter while adjusting a sensing direction of the directional antenna for each of a plurality of channels from each of the plurality of sub-carriers; Generating control information for controlling operations of the plurality of sub-transmitters based on a connection matrix indicating whether the plurality of sub-transmitters overlap each sensing region for each sensing direction, and sensing information; And transmitting the control information to the plurality of auxiliary senders.
