Abstract | In this paper, a trade-off analysis between concatenated codes consisting of a convolutional (CC) followed by a Reed-Solomon (RS) code versus low-density parity-check (LDPC) codes is presented. The analysis is based on a twofold criterion: coding gain for a target bit error rate (BER) of $10^{−6}$ and required decoder hardware complexity for a target data throughput of 10 Gbps. Furthermore, we have investigated relevant parameters which directly impact an efficient hardware implementation as well as the error correction performance of the LDPC decoder. These parameters include an attenuation factor in the min-sum layered (MSL) decoding algorithm, the finite word length of soft information and an early-termination (ET) strategy. The error correction performances are evaluated for 16-QAM modulation over an independent Rayleigh fading channel. The complexity of the RS-CC and LDPC decoders is estimated based on synthesis results using an Infineon 40 nm CMOS design kit. |

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.
