| Abstract | Link-16 is a tactical data link widely used in the United States Armed Forces and North Atlantic Treaty Organization. The communication terminal of Link-16 is called the Joint Tactical Information Distribution System (JTIDS) and features Reed-Solomon (RS) coding, symbol interleaving, cyclic code-shift keying for M-ary symbol modulation, minimum-shift keying for chip modulation and combined frequency-hopping and direct sequence spread spectrum. In this paper, we investigate the performance of a Link-16/JTIDS-type waveform in both additive white Gaussian noise (AWGN) and pulsed-noise interference (PNI) when an alternative error correction coding scheme for the physical layer waveform is employed. The waveform considered uses a concatenated code consisting of a rate r = 4 / 5 convolu-tional code as an outer code and a (31, k ) RS code as an inner code. Currently, the JTIDS waveform is received noncoherently at the chip level. In this paper the performance of the alternative, JTIDS-compatible waveform is evaluated for both coherent and noncoherent demodulation. The performance of the alternative waveform for the case where AWGN is the only noise present as well as when PNI is also present is investigated. The performance obtained using the alternative error correction coding scheme is compared to that of the existing JTIDS waveform when the same assumptions are made for both waveforms. |

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.
