Abstract
The present work describes a low-cost SDR-based
reader and demodulator for backscatter communications. This
reader can receive and demodulate signals reflected by backscatter
modules that reuse ambient waves using only open source
tools. The receiver has low sensitivity and can demodulate several
modulations; those demonstrated in this article are ASK and 4-
PAM.
