One of the main objectives of cognitive radar is to adapt the spectrum of transmit waveforms to certain needs, such as avoiding reserved frequency bands or narrowband interferences. Besides spectral requirements, good correlation properties of the transmit waveforms are also desired in specific applications, such as range compression. Moreover, practical hardware constraints usually require the transmit...
In the new paradigm of open spectrum access, the envisioned radio agility calls for fast and accurate spectrum sensing, this challenges traditional spectral estimation. In this study, we propose three new procedures that are able to sense the known spectrum of the candidate or primary user, fulfilling the requirements of open spectrum scenarios. These procedures are developed by following the framework...
The advance of cognitive radio (CR) technology put in evidence the need of new spectral estimation methods for proper labeling of licensed and un-licensed users. We present a new spectral estimation procedure for monitoring the radio spectrum. The estimate is derived from a different view point of traditional filter bank approach. The resulting method is able to detect a predetermined spectral shape...
