| Abstract | The paper proposes a novel digital signal processing (DSP) unit for an Ethernet receiver. The proposed DSP unit consists of a programmable gain amplifier (PGA), a timing recovery, a new adaptive equalizer, and a proposed baseline wander (BLW) compensator. The proposed adaptive equalizer uses 2/sup -7/ as the optimum step size, i.e., /spl mu/. Since the optimum step size is a multiple of 2, the equalizer can eliminate multipliers. Hence, the proposed equalizer has small area and consumes low power. In addition, the proposed BLW compensator implemented in a digital domain uses four symbols, including the present symbol, and can remove BLW at the channel having large BLW. To verify the performance, we simulate the proposed DSP unit using the SPW/sup /spl trade// tool. The implemented DSP unit using the 0.18 /spl mu/m SEC cell library operates at 142.7 MHz and consists of 128,528 gates. The measured BER is less than 10/sup -10/ when the transmitted data is received up to 150 m. |

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.
