Optimal Multiband Joint Detection for Spectrum Sensing in Cognitive Radio Networks
<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> Spectrum sensing is an essential functionality that enables cognitive radios to detect spectral holes and to opportunistically use under-utilized frequency bands without causing harmful interference to legacy (primary) networks. In this paper, a novel wideband spectrum sensing technique referred to as <emphasis emphasistype="boldital">multiband joint detection</emphasis> is introduced, …
