| Abstract | Parallel decoding of turbo codes is vital to the applications with very high data rates. There are mainly two existing methods for the parallel decoding of turbo codes: one is to have the sub-blocks being overlapped (OL); the other is to store the intermediate information of last iteration at the sub-block boundary (SBI). The overlapping in OL methods will slow down the decoding speed while the SBI requires some extra memory. In this paper, we present a new method which is essentially the combination of the OL and SBI but with two new features being introduced: (1) instead of storing the full information of the boundary distribution as SBI does, the proposed method only stores the index of the most probable state at the boundary and a reliability metric for initialization; (2) the boundary positions of the sub-blocks are moving in each iteration of the turbo decoding process. The proposed method outperforms the existing methods and is flexible in design and implementation. |

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.
