| Abstract | Along with the development of high-speed railway, higher and higher technical requirements for the mobile communication system in it are raised. Communication Based Train Control (CBTC) will be based on mobile communication, of which the key problem is how to support high reliability of data transmission in order to improve utilization of tracks and enhance train's safety. The applications of LDPC in reliable high-speed data transmission which serves fault monitor and early-warning system in train-ground (TG) wireless communication are proposed. The design of high-throughput and complexity reduction for regular and irregular LDPC codes has been considered in decoding algorithm and architectural in order to accord with the performance of reliable train-ground information transmission. A parallel message updates and implement method are presented for LDPC decoder of train-ground system that bring negligible loss in performance compared to the ideal case. A new implement method which is designed of very large scale integration have been proposed in this paper. The LDPC decoder has been applied in reliable train-ground high throughput fault monitor and digital early-warning communication system. Testing result demonstrates that the proposed architecture achieves a throughput of 18.629Mbps, which meets the performance requirements of reliable high data transmission and higher throughout. |

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.
