| Abstract | Space-time coding is an established technique for combating the impairments of wireless channels by means of the transmit diversity which is obtained by coding the information symbols over M transmit antennas and T symbol periods. Many existing space-time codes have good performance over the wireless channel, however, they offer small data rates compared to the actual capacity of the multi-antenna system. We study some M/spl times/T space-time block codes, for M=2,3,4 and T=2,4, with a rate of M symbols per channel use and a transmit diversity of T over a quasi-static or fast fading channel when using rotated versions of a multidimensional quadratic amplitude modulation with spectral efficiency of 2 bits per symbol. An extension to constellations with a higher spectral efficiency is also considered. We generalize the proposed codes to any number of transmit antennae M and any number of symbol periods T, such that we transmit at a rate of M symbols per channel use, and achieve a transmit diversity of T in fast fading. |

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.
