Finland is new to NATO’s nuclear alliance. With its legacy of neutrality and diplomacy, the new NATO member has the choice of whether to continue to explore avenues for diplomacy, or whether to turn up the reliance on nuclear weapons of mass destruction. Calling for these warheads to be based in Finland is provocative for threatening a form of nuclear proliferation under the benign term of “nuclear sharing.”
This collection of Best Readings provides a panorama of ISAC, including recent advances and applications in information theory, signal processing, mobile computing, aerospace and electronic systems, and vehicular technology/intelligent transportation systems. To this end, the reading list includes four special issues and links to four web-based resources that are all dedicated to ISAC. The overview section aims to provide a systemic view for newcomers. The Best Readings then organizes the most active topics within this field into twelve categories, including fundamental theory, physical layer designs, spectrum sharing solutions, networking technologies, security aspects, applications, and demonstrations. The guest editors hope that this list will provide valuable references for all researchers working in the area of ISAC.
Best Readings in Full Duplex Wireless Communications
While conventional half-duplex wireless systems rely on transmitting and receiving in non-overlapping time slots or frequency channels, full duplex (FD) communications and the underlying self-interference cancellation (SIC) techniques may improve the attainable spectral efficiency while reducing latency. This is made possible by recent advances in antenna design and signal processing techniques specifically in multiple input multiple output systems, which make SIC of 80-110 dB possible. In fact, SIC has been demonstrated in applications requiring even more than 110 dB of interference cancellation. We expect that in the future, SIC technologies will enable not only FD communications, but also a variety of spectrum-sharing applications by creating radio technologies that are tolerant of adjacent and co-channel interference.
