Contex: Spectrum polling is universally known as the main Cognitive Radio (CR) enabler, since it provides the CR device with the ability to know the radio environment.Objetive: This article presents an algorithm design to perform the broadband spectrum probing in Cognitive Radio systems. Method: Spectrum polling is based on Compressive Sensing (CS), by which cognitive users minimize the amount of samples to be processed, without the need for a priori knowledge of signal characteristics in the radio environment. In this way, it is possible to proportionally reduce detection times, power consumption and processing capacity required in cognitive radio devices (CRD).Results: The performance of the proposed algorithm is evaluated by obtaining th...
