| Abstract | This contribution presents some link and system level simulation results obtained by a WCDMA base station equipped with an adaptive antenna system. The results show that the performance gain obtained by an advanced antenna system could be substantial compared to an ordinary sector covering system. The link simulations show that for a given SIR target in a single cell system, the capacity is increased considerably compared to a conventional single sector covering antenna system. It is also shown that the difference between the different adaptive antenna algorithms is marginal. The system level simulations have shown that the capacity performance is basically proportional to the number of orthogonal beams used in the base station. In cases where the conventional three sector reference system is not truly interference limited, the performance gain can be even higher. The system simulations have also shown that using more beam positions than those defining the set of orthogonal fixed beams slightly improves the performance. However the number of beam positions can be kept relatively small, in the order of twice the number of orthogonal beams, without significant loss. |

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.
