| Abstract | In this study, the authors propose a time-modulated frequency diverse array (FDA) by combining time-modulated array (TMA) and FDA for physical-layer security. The proposed scheme has two-folds: first, the information codes are specifically designed for the FDA elements switching alternatively, which produces a specified directional pattern projecting the phase-modulation signal as a constellation in the desired range–angle section while distorting in other areas. Second, a switching scheme is adapted for the TMA according to the spreading sequence associated with the transmitted signal and the desired receiver position. In such a fashion, only the receiver located at the pre-specified range–angle position can demodulate the received signal successfully but the distorted signals radiated to other undesired range–angle positions will be difficult to demodulate by the eavesdroppers even if with the knowledge of the spread sequence. Numerical results show that, due to the range–angle-dependent characteristics, the proposed method offers more secure transmission performance and outperforms the traditional phased-array-based directional modulation method. |

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.
