Best Readings in Communications in Wireless Networked Control
Wireless networked control has attracted a lot of attention from both academia and industry in the past two decades, and has become a hot topic in recent years, mainly driven by mission-critical Industrial Internet of Things (IIoT) applications requiring closed-loop control, such as intelligent transportation, Tele-surgery, industry automation, power systems automation, and power electronics control. Specifically, a wireless networked control system (WNCS) is a spatially distributed control system consisting of networked sensors, actuators and a controller. The wireless sensors measure and report the physical process states of interest, the remote controller collects the sensors’ measurements and generates control signals, and the wireless actuators receive the control signals and control the processes. Due to its spatially distributed nature, reliable, dynamic and secure wireless communications among sensor, contro
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.
