Cyclostationary Feature Detector Experiments Using Reconfigurable BEE2

Abstract

This paper presents a comprehensive characterization of cyclostationary feature detectors through theoretical analysis, hardware implementation, and real-time performance measurements. Results of our study show that feature detectors are highly susceptible to sampling clock offsets. We propose a new detector that overcomes this limitation, and characterize its performance through experiments. In addition, the comparison with a conventional energy detector shows that feature detectors are more robust to adjacent channel interference.
