Abstract | Base transceiver stations (BTS) with antenna arrays employing narrow beam patterns pointing to each user rather than omnidirectional or directional antenna covering a large number of users or areas can provide better network performance. It is the fundamental theory of smart antenna systems (SAS) designed for a modern cellular network, which is more challenged nowadays by network capacity and service quality due to the increased Internet traffic volume. In this paper, super-resolution algorithms are applied to the switched beam smart antenna system, and a higher angle resolution and performance are achieved. This paper presents super-resolution algorithms specifically developed for the switched beam smart antenna system. The particular research interest is focused on the performance of a multiple signal classification (MUSIC) algorithm and a RELAX algorithm. The study results show a higher angle resolution and a significant overall system benefit by using these two algorithms. We also discuss the non-uniform geometry arrangement of the array and its application to improve the capacity of direction finding further. Simulation results are presented. |

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.
