| Abstract | Power line communications provide a convenient and cost-effective solution for data transmission, because power mains are the most popular and widely distributed medium in the world. However, the time-variant and unpredictable channel environment for communication poses a major challenge. In this regard, we propose a robust power line modem based on adaptively signal detection techniques for networked home appliances. The modulation scheme used in this research is a chirped spread spectrum with a separate matched filter based on an adaptive threshold decision technique. In addition, we propose an adaptive retransmission technique based on flexible carrier frequency selection using a ram based look-up table (LUT) for improving carrier sense multiple access with collision avoidance (CSMA/CA) media access protocol. The proposed power line transceiver is realized in 0.35 mum CMOS technology and verified with networked various consumer electronic devices. The results show that the proposed power line communication modem is well qualified as a communication device for home automation . |

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.
