| Abstract | Space-time block coding (STBC) is a signaling algorithm utilizing multiple transmit and receive antennas in order to improve the system performance and increase the channel capacity in the presence of fading and interference. This paper introduces Prerake space-time block codes (PRK-STBC) for multiuser direct-sequence code-division multiple-access (DS-CDMA) systems operating in time-division-duplex (TDD) mode. PRK-STBC combines both antenna diversity and temporal precoding. In a DS-CDMA system, the transmit antennas are available to all users at all the time. In a multipath channel, the prerake coding of the transmitted signals results in multipath diversity, without the need of rake receivers at the mobile stations. Hence, only simplified mobile receivers are needed and most of the signal processing is done at the base station. The performance of PRK-STBC is examined in multipath fading. The performance is also investigated against the used number of transmit and receive antennas (up to four transmit antennas and one receive antenna are considered in the simulation). |

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.
