In this chapter, dynamic wideband signals with high sampling rate are analysed through the discrete Stockwell transform (ST). To this end, a reduced complexity ST-based transform with independent time and frequency resolution is investigated. We call it dual-resolution approach. It results in a new strategy based on a trade-off between the...

Technologies such as cognitive radio and dynamic spectrum access rely on spectrum sensing which provides wireless devices with information about the radio spectrum in the surrounding environment. One of the main challenges in wireless communications is the interference caused by malicious users on the shared spectrum. In this manuscript, an...

SHIELD technology demonstrators have been conceived to illustrate the functionalities of specific security, privacy, and dependability (SPD) technologies that, being domain independent, might be adopted in several application scenarios. The selected technologies have been introduced in Chapter 3, while this chapter provides more detailed...
