| Abstract | RFID systems use backscattering communication in which the TX transmits a continuous wave (CW) to provide energy to the tag while the RX receives data from it. Due to the simultaneous operation of the RX and TX, large TX leakage is the main issue in securing RX sensitivity. Although external isolation components such as a circulator or directional coupler are widely used in RFID systems, TX leakage is still a dominant source of sensitivity degradation due to its finite isolation and environmentally dependent antenna reflection ratio, as shown in Fig. 5.6.1(a). In a single-antenna-based RFID system, the TX carrier leakage is typically above 0dBm at the RX input despite off-chip isolation components [1]. As can be seen in Fig. 5.6.1(b), when the close-in phase noise of the TX carrier is -85dBc/Hz, the phase noise level of 0dBm TX leakage in the receive channel reaches 89dB higher than the thermal noise level, thus directly degrading the SNR. In efforts to solve the leakage problem, leakage cancellation [2,3] and self-correlated RX [4] techniques have been reported. However, high power consumption for leakage replica generation and long calibration time, as in [2,3], and hardware complexity for a 45 degree phase shift [4] are issues that need to be resolved. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
