Abstract | The authors apply spatial modulation over multiplicative complex fading wireless channels, where the multiplicative complex fading is represented by the product of K statistically independent and identically distributed standard complex Gaussian random variables, where K ≥ 2. The analytical bit-error rate (BER) approximation of symbol estimation is obtained in terms of a Meijer's G function. The conditional pairwise error probability (PEP) of transmit antenna index estimation is a function of a stochastic parameter with an unknown distribution function. The authors propose a lognormal distribution to approximate the distribution of this stochastic parameter. Based on the lognormal distribution, the average PEP and the analytical error probability upper bound of transmit antenna index estimation are derived. A goodness of fit test successfully validates the proposed lognormal distribution being the approximate distribution of the stochastic parameter. The derived analytical BER approximations for both symbol and transmit antenna index estimation are successfully validated via Monte Carlo simulations. |

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.
