| Abstract | Joint beamforming with receive combining is a simple method for exploiting the significant diversity provided by multiple-input multiple-output (MIMO) systems, and the use of orthogonal frequency division multiplexing (OFDM) enables low complexity implementation of this scheme over frequency selective MIMO channels. In this paper we analyze the combination of MIMO systems with OFDM using joint beamforming in the multi user case where the receiver and the transmitter are equipped with antennas arrays in the reception and emission respectively. Under the assumption that all users' channel state information (CSI) is available at each of the users, we will investigate the performance of conventional multi-user detector in the context of an uplink MIMO- OFDM system. Furthermore, we discuss orthogonal joint beamforming design schemes with matched filter receiver. Joint design of transmit and receive beamvectors are addressed. From this perspective, a set of design criteria can be easily accommodated and efficiently solved even though closed form expressions may not be available. Results shows that these criteria remain available in multiuser case and have the same performance classification then single user case. |

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.
