Modulation Schemes of SDR for RFID Signal Transmission Performance Evaluation

This paper presents a performance evaluation of a radio frequency identification (RFID) signal-transmission framework in software-defined radio (SDR) using phase shift keying and quadrature amplitude modulation schemes. The RFID signals were compared within the SDR framework with respect to SDR performance. The SDR system performance was evaluated by analyzing signal transmission, estimating bit-error rate and comparing signal-to-noise ratios (SNR), with satisfactory results. The eye diagrams were also computed and compared with the SNR to evaluate the SDR signal-transmission performance.
