A Radio Frequency Identification Technology-Based Positioning and Interference Suppression System for Library Books

Large scale path loss modeling plays a fundamental role in designing both fixed and mobile radio systems. Wireless system are complex systems, so that prediction of the radio coverage is not done in an exact manner. Therefore before setting the system we need to choose a proper model of predicting path loss and interference. These proper methods depend upon the system environment, desired radio coverage and system frequency. In this paper of predicting path loss and interference analysis of UHF-RFID, we try to eliminate the problems associated of positioning and interference suppression system of library books to RFID systems. Simulation results show that the proposed method can thus improve overall system performance substantially.
