| Abstract: | MATLAB controlled oscilloscope was used to implement the acquisition of analog signal from the reader of SAW RFID system, and to acquire the coded echo signal of the tag displaying on the oscilloscope.Data display could be designed in MATLAB on the computer and the coded echo signal of the tag was demodulated and processed with the maximum correlation method, thus SAW RFID system was established in the end. |
