| Abstract | The use of antenna arrays at both ends of the link has attracted significant attention of the researches on space-time equalization and coding techniques for so called multiple-input-multiple-output (MIMO) channels. The presence of strong co-channel interference (CCI) in addition to inter-symbol interference (ISI) in current wireless (mobile) communication systems places a significant challenge to MIMO space-time equalizers. We assess the performance of BLAST/MIMO on frequency-selective MIMO channel model in the presence of CCI. Space-time processing is used in order to deal with the frequency selectivity and to provide more degrees of freedom to deal with cochannel interference. We consider two non-linear space-time processing-based receivers. The first one is a MIMO space-time decision feedback equalizer (MIMO ST-DFE) and the second one is a space-time delayed decision feedback sequence estimator (MIMO ST-DDFSE) with actual adaptive algorithms for channel acquisition. Noise-limited as well as interference-limited situations are evaluated. |

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.
