| Abstract | Zigbee standard has all set of protocols which supports low data rate, low power consumption, low cost and short range communications. The main application of Zigbee is Wireless Sensor Networks(WSNs). In digital communications, data is being transmitted by converting input bit stream in to sample functions of analog waveforms. When the analog RF signal passes through bandlimited channel, it results signal degradation in terms of symbol delay, carrier frequency and phase offsets. Various synchronization techniques can be used to estimate these characteristics in coherent receivers. In this paper, phase offset can be estimated using costas loop carrier recovery circuit and early late gate timing recovery algorithm is used to estimate symbol timing before data being decoded. The receiver performs well for different SNR (Signal to Noise Ratio) values varying from -10dB to 14dB. Transceiver system design is developed using Matlab Simulink and its performance can be analysed when it undergoes through Additive White Gaussian Noise (AWGN) channel and Rayleigh fading channel. |

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.
