The MS thesis document by Robert Corless on the topic of microwave frequency-hopping for backscatter is now available for download on the Georgia Tech server:
MS Thesis: Part 15 Compliant Frequency Hopping Backscatter Communication at 5.8 GHz
In this work, the author discusses the unique challenges and opportunities of implementing a frequency-hopping scheme for backscatter communications. The author even designs and implements a frequency-hopping algorithm on the GTPG’s custom frequency hopping board, consisting of a programmable microcontrollers and voltage-controlled oscillator + phase locked loop chips.
