Energy detector with adaptive sensing window for improved spectrum utilization in dynamic cognitive radio systems


Cognitive radios (CR) are regarded as a viable solution to enabling flexible use of the frequency spectrum in future generations of wireless systems by taking advantage of spectrum holes, that is idle frequency bands not actively used by primary users (PU) for licensed transmissions. The actual utilization of a spectrum hole is determined by its duration… (More)
