This paper presents a novel cyclostationary signature detector designed for robust detection of embedded signatures under frequency-selective fading conditions. Cyclostationary signatures are features which may be intentionally embedded in a digital communications signal, detected through cyclostationary analysis and used as a unique identifier. It has been shown that such signatures can also be employed to derive key signal parameters including carrier frequency and bandwidth, making them a powerful tool to support network coordination in dynamic spectrum access scenarios.
