| Abstract | Multi-mode and multi-standard connectivity has become a necessity for portable communication systems. A convenient architectural solution is to build flexible systems that can be reprogrammed to meet requirements of multiple standards. One of the major issues in this context is the resource overhead required by programmability. In particular, in the latest VLSI technology nodes, energy consumption has become a very severe problem, greatly impacting the reliability of the hardware. Therefore, any design aimed at the implementation of multi-mode multi-standard communication systems must be strictly targeted at the lowest power consumption without jeopardizing peak performance, while, at the same time, retaining a high degree of flexibility. This work presents the design and implementation of a (auto)correlator block for timing synchronization. The design is composed of a scalable computational unit, which allows to meet real-time requirements of different wireless communication standards (e.g. W-CDMA, IEEE 802.11a/g/n). Moreover, dynamic power management allows to dynamically trade-off energy consumption versus performance, adapting power dissipation to the specific requirements of each supported standard, as well as to follow dynamic variations of the computation load. |

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.
