A robust two-stage spectrum sensing method using filter bank based energy detector and fourth order cumulants for cognitive radios
Recent years have shown a growing interest in the concept of cognitive radios (CR), in order to access the electromagnetic spectrum in an opportunistic way. Such systems require efficient spectrum detectors able to work in low signal-to-noise ratio (SNR) environments, with little or no information a...
