Evaluation of the wideband compressive radio receiver for spectrum sensing

Abstract

We present an empirical evaluation of the carrier detection method used in the Wideband Compressive Radio Receiver (WCRR), which is of particular interest for spectrum sensing in Cognitive Radio (CR) and Dynamic Spectrum Access (DSA). We study the effect of different combinations of the decimation factor L, and window lengths, N. We then assess the robustness of the carrier detection method to noise. We find that the WCRR should be a viable option for wideband spectrum sensing using readily available Analog to Digital Converters (ADCs)
