Chris Valenta designed the R.E.S.T. platform, a modular 5.8 GHz backscatter platform with a software radio reader that could be configured for a limitless combination of sensors, antennas, power sources, and modulation schemes. The R.E.S.T. … [Continue reading]
A lecture on the history, use, and backscatter applicability of balance codes. Balance codes (also called recording codes, channel codes, line codes, or modulation codes) have been used in magnetic tape drives, swipe cards, optical disks, and many … [Continue reading]
This lecture discusses the receiver architecture of a backscatter reader, explaining the nature of coherent detection and direct down-conversion. The nature of these receivers introduces interesting behavior in terms of noise, sensitivity, and … [Continue reading]
