Available in PDF, EPUB and Kindle. Book excerpt: Radio Frequency Identification (RFID) is a wireless technology used to automatically identify objects attached to its tags. Its applications span in different areas such as inventory control, logistics, security and item tracking. Vast majority of commercially available RFID tags use Application-Specific Integrated Circuits (ASICs) to encode and transmit data. This micro-chip in the RFID tag makes the tag manufacturing process complicated and expensive compared to optical barcode printing. Researchers have brought the idea of removing the micro-chip and using chipless techniques to encode data into tags, allowing them to be passive, printable and low cost. However, chipless RFID technologies have still not been able to replace relatively expensive chipped RFID tags mainly due to less tag bit capacity. Over the last decade, researchers have mainly focused on improving the chipless RFID tag design and the RFID reader architecture. However, they were mostly using primitive signal processing techniques such as moving average or threshold based detection. The few advanced signal processing techniques reported so far have high computation complexity, hence not feasible for commercial implementation.This thesis presents smart tag detection techniques that are computationally feasible and allowing high tag data encoding capacity. Firstly, four different maximum likelihood (ML) based tag detection techniques have been developed based on the reader architecture and channel knowledge. In addition, all of them are able to operate based on both the time and frequency domain data samples of any frequency domain tag. One of the detection techniques jointly detects the channel as well as the tag type without having any prior channel knowledge or a calibration tag. A fifth tag detection technique was developed for an existing frequency domain tag reader using the magnitude of the tag response. However, these single input single output (SISO) based tag detection techniques suffer from high computation complexity. Two new detection methods have been developed using the likelihood expressions derived in above techniques to reduce the computation complexity from exponential to linear order. The first method was a suboptimal bit by bit detection technique (serial reading) and the second method is a fully optimal Trellis tree based Viterbi decoding technique. Then a novel, multiple input multiple output (MIMO) based chipless RFID system was introduced and a tag detection technique for the proposed system was developed. Finally a MIMO chipless tag was designed which includes a broadband equal power divider, monopole antennas and spiral resonators.It was found that, the proposed tag detection techniques for SISO systems provides significantly higher tag reading accuracy over the existing threshold based detector. In addition, they are capable of operating without a guard-band which makes the tag data bit capacity to be doubled without compromising the reading accuracy. Moreover, the effective SNR gain provided by the proposed techniques can be represented as increasing the tag reading range. All these benefits were achieved without compromising the low computation complexity. The MIMO tag with 2 branches is capable of encoding up to 4 times the total bits stored in existing SISO tags.These smart tag detection techniques are expected to increase the data bit capacity in chipless RFID tags hence produce commercialized chipless RFID systems in future.

Download or read book Chipless RFID Authentication written by Zeshan Ali and published by John Wiley & Sons. This book was released on 2022-08-24 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chipless RFID Authentication examines the development of highly secure product authentication systems for manufactured products by using chipless radio frequency identification (RFID) technology. The absence of a chip and its compatibility with mass production make chipless RFID an alternative to barcodes. This book discusses how, by using natural randomness inherent to the fabrication process, each chipless RFID tag has a unique signature that can never be reproduced, even if someone tries to copy the label. The book first explores the state-of-the-art of existing authentication and anti-counterfeiting methods based on their security level. Next, a methodology describing the characterization of chipless RFID tags for the authentication application is presented, followed by a discussion of the extraction of aspect-independent parameters for chipless RFID tags. After proposing designs for the tags, the book presents the realization and characterization of the labels (which exhibit naturally occurring randomness) for authentication, using printed circuit boards and inkjet printing on polyethylene terephthalate.

Download or read book Signal Processing Methods for Chipless RFID written by Prasanna Kalansuriya and published by . This book was released on 2014 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radio frequency identification (RFID) is a technology that automates routine procedures of data extraction, identification, tracking and surveillance in applications such as inventory control and logistics. The unit cost of conventional RFID tags is too high for them to be used in large item level tagging applications. This is because of the expensive electronic integrated circuits (ICs) used in the tags. As a solution to further reduce the cost of RFID tags, chipless RFID tags have been developed. A chipless RFID tag does not require an IC for its operation.Current research on chipless RFID technology has been focused on, the development of tag designs with enhanced data capacity, the development of tags with sensing capabilities, and the development of RFID reader architectures and signal processing algorithms. Despite current research efforts, further work is required in the area of signal processing for chipless RFID. For this purpose, three novel signal processing methods are introduced in this thesis, (i) development of a robust multidimensional detection algorithm for detecting data bits encoded in a chipless RFID tag, (ii) time and frequency domain analysis of backscattered tag signals for the removal of interference, and (iii) a new systematic calibration procedure for single antenna RFID readers. These methods enhance the performance of chipless RFID systems in terms of the data bit detection and reading range. Existing algorithms used for detecting data bits encoded in a frequency signature of a chipless RFID tag use a one dimensional approach to detection. The one dimensional approach to detection does not consider all the characteristics of the spectral features that encode data bits in a frequency signature. Therefore, the detection performance achieved is suboptimal. In order to enhance the detection performance, a new multidimensional detection method is introduced. The new method utilizes a set of orthonormal basis functions to fully describe the characteristics of a frequency signature. Using these orthonormal basis functions a frequency signature is represented as a signal point in a multidimensional signal space. The detection of data bits contained in an unknown frequency signature is performed using minimum distance detection. It is shown that the performance achieved by the new method exceeds the performance of existing one dimensionalthreshold based detection of tag data bits.The second method proposed in the thesis focuses on improving the reading range of an RFID reader beyond proximity based reading. For this purpose, the total received signal at an RFID reader is analysed in the time domain as well as the frequency domain to identify the essential signal component that contains the tag data. It is shown that the useful data is contained in the antenna mode of the backscattered tag response. The antenna mode backscatter is separated from therest of the received signal using a time window. The separated antenna mode is then analysed in the frequency domain to estimate the tag's frequency signature. Through this time and frequency domain analysis, non-proximity based reading is achieved. It is shown that the tag can be read in non-proximity reading conditions using simulation results and measurements taken in an anechoic chamber environment.The final method introduced in the thesis is a systematic calibration procedure for single antenna based chipless RFID readers. The calibration procedure takes into account practical conditions prevailing in a real world application environment. The calibration allows the RFID reader to accurately estimate the frequency signature of a chipless RFID tag in a cluttered environment. It also addresses the limitations of existing calibration methods used for chipless RFID systems such as the need for repeated calibration and antenna alignment.
