“…This approach is followed for instance in the study by [35,37,57,58] for RFID tags or in [42,59] for RFID readers. Furthermore, the approach of an automatic generation of hardware modules out of highlevel descriptions, as it is common practice in chip design [60], is demonstrated on the example of encoding and decoding units in RFID [61,62]. Untangling standard compatibility issues and automating the design flow for a multi-standard active RFID tag are addressed in the study by [63].…”

Today's RFID systems exhibit relatively little functionality, while future systems and ubiquitous computing applications require an ample set of general purpose features, like wide communication ranges, high data rates, high reliability, and many more. In order to meet these high-performance goals, several challenges in state of the art RFID systems need to be managed: (1) the compatibility of RFID equipment, working according to different standards in various frequency domains, (2) the thorough understanding of the performance impact of physical layer system parameters, (3) the venture of novel wireless technologies in the context of RFID, and finally, (4) to deal with the increased complexity of high-performance RFID systems. Therefore, designers desire a highly configurable, flexible, and high-performance RFID environment to experimentally explore the underlying physical conditions and to evaluate novel RFID technologies and designs. This paper introduces the concept of rapid prototyping in RFID and provides a survey of system simulators, demonstrators, and rapid prototyping environments. A guideline for the setup for such a rapid prototyping system applicable for RFID is presented, and its implementation is demonstrated. Finally, some exemplary measurements carried out with this rapid prototyping system are presented.

“…The modulation techniques in RFID physical (PHY) system [7] are based on conventional digital modulation schemes like Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), Phase Shift Keying (PSK) and Quadrature Amplitude Modulated (QAM). Reference [8] presents optimized ON/OFF states for the ASK modulated passive RFID tags, considering both the reader receiver sensitivity and the tag antenna mismatch conditions.…”

DCSK modulation in chaos communication is a robust non-coherent modulation scheme. In this paper, the multiple-access DCSK scheme based on the OVSF code is proposed. Using the multiple-access DCSK scheme in RFID system, a DCSK-RFID system is presented. In the presented DCSK-RFID system, we use the DCSK for tag modulation for its low complexity and the simple receiver of the DCSK scheme is applied in reader part. The tag's BER performance of the proposed DCSK-RFID system is carefully generalized both in theoretic analysis and in simulations. From the simulation results, the theoretical and simulation values match closely with each other. Then, we design an anti-collision MAC protocol based on multi-access DCSK-RFID scheme. We theoretically analyze the throughout in given number of tags. The simulation shows that the proposed algorithm has better throughout than S-Aloha system.

“…If the improved Miller is employed, it can easily solve the energy problem. However, the extraction of bit timing signals is complicated during the decoding [4], so a specialized decoding circuit is needed. Because of the previously mentioned limitations of traditional methods, a new improved encoding method is proposed in this letter.…”

To fit the limited volume and power consumption of the passive radio frequency transmission system of the electronic time fuze, an improved coded mark inversion (CMI) is proposed in this letter. From the performance analysis, the energy transmission efficiency of this encoding method is at least 50% higher than that of CMI and NRZ. Finally, the experiment results show that by adopting this improved CMI, the change of DC voltage through magnetic coupling is lower than 0.2 V when the accuracy of data transmission is above 99.5%.
