초록
Spectrum sensing is a basic function of cognitive radio systems which detects spectrum holes. The spectrum sensing and spectrum access is a classic exploration vs. exploitation problem for cognitive radio overlay networks, where the unlicensed secondary users access the idle portion of licensed primary users. We propose a simple independent spectrum sensing architecture which can handle cooperative spectrum sensing for either coordinating or non-coordinating secondary users. The output hypotheses from secondary devices are combined by a simple algorithm to achieve better performance.
