Combined compressive sampling and distribution discontinuities detection approach to wideband spectrum sensing for cognitive radios
ICUMT 2011, 3rd IEEE International Conference on Ultra Modern Telecommunications, 5-7 October, 2011, Budapest, Hungary
This paper 1 presents a new sensing technique for cognitive radio systems which combines algebraic tools and compressive sampling techniques. The proposed approach consists of the detection of spectrum holes using spectrum distribution discontinuities detector fed by a compressed measurements. The compressed sensing algorithm is designed to take advantage from the primary signals sparsity and to keep the linearity and properties of the original signal in order to be able to apply algebraic detector on the compressed measurements. The complexity of the proposed detector is also discussed and compared with the energy detector as reference algorithm. The comparison shows that the proposed technique outperforms energy detector in addition to its low complexity.
