Demonstration of Real-Time Spectrum Sensing for Cognitive Radio
IEEE Communications Letters
The requirement for real-time processing indeed poses challenges on implementing spectrum sensing algorithms. Trade-off between the complexity and the effectiveness of spectrum sensing algorithms should be taken into consideration. In this paper, a fast Fourier transform based spectrum sensing algorithm, whose decision variable is independent of noise level, is introduced. A small form factor software defined radio development platform is employed to implement a spectrum sensing receiver withdoi:10.1109/lcomm.2010.082610.100725 fatcat:pqhhhijtvzeghozjsjndzaq5ta
