Abstract | Nowadays, the construction and application of underwater acoustic (UWA) networks has received much focus in the research area of UWA communication. This paper constructed an underwater acoustic modem based on two types of spread-spectrum technique, frequency-hopping (FH) and direct sequence spread spectrum (DSSS), correspond to quaternary frequency shift keying (4FSK) and differential binary phase shift keying (DBPSK) modulation respectively. Automatic gain control algorithm, synchronous tracking, and channel coding and interleaving also were studied. A four-node multi-hop network was constructed using this underwater acoustic modem, and has been proved by several experiments in the pool and sea. The dual-mode acoustic modem may be used to build more complicated underwater acoustic communication network in the future. |

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.
