| Abstract | Space-time block coded spatial modulation (STBC-SM) with cyclic structure (STBC-CSM) employs cyclical rotation of activated transmit antenna pairs to transmit Alamouti codewords taken from two different constellation sets to improve the spectral efficiency of STBC-SM. Furthermore, existing literature has shown that media-based modulation (MBM), which employs radio frequency (RF) mirrors demonstrate significant improvement in error performance of wireless systems. Hence, this study proposes the application of MBM to STBC-CSM and STBC-SM in the form of media-based STBC-CSM (MBSTBC-CSM) and MBSTBC-SM, respectively. The theoretical framework of the union-bound on average bit-error probability of M-QAM MBSTBC-CSM and MBSTBC-SM, for the maximum-likelihood (ML) detector is formulated and agrees well with Monte Carlo simulations. Furthermore, due to the large computational complexity of the ML detector, the authors propose a low-complexity near-ML detector for MBSTBC-CSM and MBSTBC-SM, which achieves a near-ML bit error rate performance with 41 % reduction in computational complexity. |

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.
