Abstract:
This paper presents an enhanced anti-interference technique for passive RFID wireless signals operating in complex electromagnetic environments. The proposed method integrates a Blind equalization algorithm with frequency-based authentication to improve signal robustness and transmission reliability. Unlike conventional approaches that address interference in isolated stages, the proposed framework jointly mitigates multipath fading and electromagnetic interference while ensuring signal authenticity. A simulation model based on Rayleigh fading channels and digital modulation schemes (BPSK and 16-QAM) is developed to evaluate system performance. The results demonstrate a significant reduction in bit error rate and improved signal stability under varying signal-to-noise ratio conditions. Additionally, the proposed method enhances effective read range and reduces collision effects in multi-reader scenarios. The technique is particularly suitable for aviation applications, including passive RFID-based baggage tracking systems, where high reliability and interference resilience are critical. The findings confirm that the integration of blind equalization and frequency authentication provides a scalable and efficient solution for next-generation RFID systems.
