| Abstract | In this paper, we investigate the performance of a bit-interleaving diversity (BID) scheme formultiple packet transmissions over multiple-input multiple-output (MIMO) frequency-selective channel in the context of hybrid automatic repeat request protocols. We show under the maximum likelihood decoding rule that a BID scheme outperforms an identically interleaved transmit scheme. Moreover, we identify and characterize three types of diversity resulting from the BID scheme: modulation diversity, multiplexing diversity, and interference decorrelation resulting in an enhanced detection performance. By using a distance spectrum analysis, we evaluate their respective importance according to the used modulation and the transmission scenario. Some interleaving design rules are given in order to enhance further the overall transmission diversity. The receiver is implemented using a turbo-equalizer structure with packet combining based on separate linear equalization followed by joint decoding. Simulation results show the efficiency of the BID scheme for different transmission scenarios. |

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.
