| Abstract | The transmitter identification (Tx-ID) of digital television (DTV) systems becomes crucial nowadays. However, identification of a weak source signal is quite difficult, and therefore pseudo-random (PN) sequences were proposed to be embedded into the DTV signal for the Tx-ID purpose. Kasami sequences are excellent candidates adopted for the Tx-ID PN sequences as they provide a large family of nearly-orthogonal codes. We envision that, in the future, different broadcasting companies may use different Tx-ID sequences (codes) just as different telephone companies have owned different code prefixes or “area codes”. Tx-ID sequences may be grouped separately for different companies and hence there is an emerging need to categorize Tx-ID sequences just as ZIP codes are used to categorize postal addresses. In this paper, we are particularly interested in the Tx-ID sequences made of Kasami sequences. Our main objective is to efficiently categorize and address Kasami sequences. We design a new algorithm that can efficiently classify Kasami sequences within $O(n^{1.5}$ $log^{2}$ n)-time, where n is the sequence length. Simulations show that our proposed algorithm is very fast in practice. Our proposed new blind detection method for determining the addressing parameters for an arbitrary Kasami sequence can save the required huge memory storage space by the conventional correlation-based Kasami sequence classifier (detector). |

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.
