| Abstract | Hybrid hard decision-soft decision (HD SD) decoding is a novel decoding technique for Reed Solomon (RS) codes. HD SD decoding utilizes traditional hard decision RS decoding where the received block is either decoded correctly or a decoding failure exists. In the event of a decoding failure, channel reliability information is used to identify received code symbols with a low probability of being correctly received and to generate new code symbol estimates that are used in the traditional RS decoding algorithm. HD SD RS decoding was developed for use with bandwidth efficient modulation schemes such as M-ary phase-shift keying). Since many communication systems use orthogonal modulation schemes such as M-ary frequency-shift keying (MFSK) for more robust communication links, this paper presents the performance simulation and analysis of MFSK with RS encoding, hybrid HD SD decoding, and noncoherent demodulation. In addition to AWGN, the effects of pulse-noise interference (PNI) are considered. An interesting result is that hybrid HD SD decoding has better performance and error correction capability than either traditional HD decoding or other RS SD techniques that have been examined in the literature, especially when PNI is present. |

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.
