Abstract

An optimal joint multiband-sensing framework is studied to maximize the throughput in cognitive radio networks. Convexity range for this non-convex framework is calculated under certain channel conditions keeping either sensing time or threshold constant. Also joint convexity range for both sensing time and threshold is determined. Waveform based detection, which is accurate and better than other detection schemes in terms of reliability and convergence time, is applied.
