New YouTube video on on the topic of DVB-S2 modulation for satellite video. This was a lecture that I captured in Shenzhen last year as part of a “refresh” of topics in the Satellite Communications course. Learn about the second generation upgrades to the Digital Video Broadcasting — Satellite Gen 2 standard.
Here is an article from several years ago that talks about the future of wireless power transfer, with a few GT quotes sprinkled in for good measure. A quote about our ECE senior design students:
“Wireless power could enable a whole new class of devices,” says Durgin. Those devices will include sensors on all the mechanics of a home, business or factory; detectors for heat, light and motion; and cameras and controls that we can move and upgrade at our convenience, without ever having to touch the building’s wiring. These controls will include “peel and stick” light switches and thermostats, which are already a common senior design project among Professor Durgin’s students.

A portion of Yang Qian’s PhD research is now available on IEEExplore. Her original conference paper from IEEE RFID 2018 explores using various Kalman filters as part of the GTPG’s Hybrid Inertial Microwave Reflectometry (HIMR) positioning scheme. This technique uses RFID-like tags to localize nodes within a few mm of their actual position.

In this paper, we outline the benefits of subdividing a retrodirective array into segments and using MIMO-style (multiple-input, multiple-output) signaling to reflect multiple streams of independent data back to a reader. The rules for making this happen are different than a conventional MIMO link.
