| Abstract | A blind multiuser receiver is proposed for multiuser detection of UWB systems in a realistic indoor channel. The proposed blind multiuser receiver is based on the constant-modulus algorithm (CMA), which is known to provide satisfactory performances in a blind setting. In order to overcome the CMA interference capture problem typical of a multiuser scenario, we propose to adopt a two stage receiver: in the first stage, partial ISI and MA1 suppression is achieved by exploiting the desired user signature structure properties; in the second stage, based on CMA, the residual MAI and the ISI are removed, and the desired symbols are reliably recovered. Computer simulations show that, the proposed detector achieves good performances . |

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.
