SDR Based Energy Detection Spectrum Sensing in Cognitive Radio for Real Time Video Transmission

Blog Article

Cognitive radio is a budding approach which helps to address the imminent spectrum crisis by dynamic spectrum allocation and support the increased data traffic with an intelligent mechanism of Software Defined skull bride and groom Radio (SDR).SDR avoid the frequent modifications in the hardware structure with the use of software defined protocols.The main novelty of the paper is an effective implementation of CR using energy based spectrum sensing method which is done on GNU radio for real time transmission of video as a primary user.From evaluation results, one can see that the proposed system can indicate the tokidoki hello kitty blind box frequency band occupancy by setting the detection output.

Detection output changes to one with start of video transmission.Motivation behind this work is design of a spectrum sensing method which is best suited for detection of white spaces during the transmission of video as a primary user on SDR platform.
