| Abstract | A novel space-time turbo coding modulation technique is presented in this paper. At the encoder, information bits are encoded using a concatenated space-time turbo coder, and then coded symbols are modulated and assembled by a pre-defined function rather than punctured as in other schemes. It can achieve lower code rate (because it doesn't puncture the coded signals), get more coding gains and take advantage of both space and time diversity. Since its decoding need to calculate two extrinsic probabilities simultaneously, traditional log-map decoding algorithm fails to be used directly. An extended 2-dimensional Log-Map decoding algorithm is developed to decode the proposed scheme. Simulation results and theoretical analysis exhibit its excellent performance. Under the same conditions, the proposed scheme will bring about 12 dB gains at BER 1.0 e-5 over some other known schemes at quasi-static fading channels, and above 10 dB at BER 1.0 e-5 over time-varying fading channels. |

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.
