| Abstract | This paper presents a high-throughput structured low density parity check (LDPC) code and an optimal parallel decoder architecture with advanced Ping-Pong RAMs for the HINOC 2.0 systems. An additional iteration scheme is proposed to further improve decoding performance by taking full use of time intervals of the discontinuous streams, an important feature in HINOC 2.0 systems. The proposed LDPC code proves to be of better performance than the codes adopted in the current standards (802.16e). The proposed decoder is implemented and synthesized on FPGA Stratix V, with the maximum working frequency of 145MHz. The total resource cost is reduced by 23%, which is the cost of one decoder core, with slightly increased complexity in control logics, compared with the traditional Ping-Pong RAM based parallel architecture. The resulting performance is 2Gbps which is enough to support HINOC 2.0 systems. |

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.
