摘要：
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.
