| Abstract | Direct sequence spread spectrum is one of the three fundamental techniques (other two are FHSS and THSS) of Spread Spectrum communication. In DSSS the digital information signal or user data is multiplied with a high-bit rate Barker code to spread the spectrum. After spreading the spectrum, before transmission the consequential wider bandwidth information signal is modulated using fixed carrier frequency. Beside other advantages, DSSS provides the inherent transmission security. This paper presents a proposed scheme that enhances the transmission security of the existing traditional DSSS communication system by using Barker code along its binary compliments (1's and 2's) as the spreading codes. This proposed work clearly shows the enhancement in transmission security with the help of comparative example. Here, 11-bit Barker code is used to spread the spectrum; however, other spreading codes having any bit-size may also be used instead of 11-bit Barker code. |

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.
