Wideband Spectrum Sensing: A Bayesian Compressive Sensing Approach [PDF]
Sensors, 2018 Sensing the wideband spectrum is an important process for next-generation wireless communication systems. Spectrum sensing primarily aims at detecting unused spectrum holes over wide frequency bands so that secondary users can use them to meet their requirements in terms of quality-of-service. However, this sensing process requires a great deal of time,

Advanced Energy Detector Based Cooperative Spectrum Sensing In Cognitive Networks
MATEC Web of Conferences, 2016 Cognitive radio is a befitting hopeful technology for future. Spectrum sensing is the most critical function of cognitive radio. Most of the spectrums sensing processes proposed earlier become impractical at lower signal to noise ratio conditions.

Convex Sensing-Reporting Optimization for Cooperative Spectrum Sensing [PDF]
IEEE Transactions on Wireless Communications, 2011 We consider the cooperative spectrum sensing problem in cognitive radio with energy detection. Secondary users with non-identical, independent sensing channels make 1-bit sensing decisions and report their decisions to the secondary base station over orthogonal fading channels. The base station acts as a fusion center by combining the decisions with OR-
