| Abstract | This paper studies joint transmitter and receiver design for the space-time block coding and spatial multiplexing hybrid communication system with limited feedback. Existed QR group receiver uses QR decomposition of the channel matrix to separate the filtered versions of the multiplexed space-time coded symbol blocks followed by space-time decoder, and the performance of this scheme is usually limited due to diversity lack of the earliest detected block. To overcome this problem, in this paper each space-time data block adaptively selects the appropriate transmit antenna group according to channel state information. Furthermore, this transmit antenna grouping can be derived with low complexity using successive QR decomposition of channel matrix at the receiver, thus only the index of antenna grouping result in a predetermined codebook is needed to fed back to the transmitter. The performance of the proposed schemes is evaluated in correlated channels through computer simulations. |

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.
