| Abstract | In this paper, the performance of the space-time coding ultra wideband impulse radio system in a typical IEEE 802.15 multipath channel is studied. In the proposed scheme, only two transmit antennas and one receiver antenna are employed and no channel information feedback is needed. We investigate how the temporal and spatial diversity influence the multiple access performance and how the space-time coding technique is used to mitigate the multiple access interference (MAI) and the inter-symbol interference (ISI) thereby improves the bit error rate performance of the ultra wideband impulse radio system. Numerical results show that the space-time coding technique is an efficient means to improve the performance of ultra wideband impulse radio system under IEEE 802.15 multipath environment in both one single user and multi users environment. |

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.
