| Abstract | We consider the transmission of discrete-time continuous amplitude source information symbols over Multiple-Input Multiple-Output (MIMO) Broadcast Channels (BCs) using analog Joint Source Channel Coding (JSCC). We propose a distributed scheme that consists of single-user analog mappings concatenated with a BC access scheme specifically designed for the BC. Two different access methods are considered depending on the level of channel knowledge at transmission: Code Division Multiple Access (CDMA) and linear Minimum Mean Square Error (MMSE). The resulting analog JSCC systems are optimized to satisfy the requirements corresponding to the user MSEs and the power constraint. The idea of MSE balancing is also introduced to guarantee the feasibility of the optimization problems. Computer simulations show that CDMA provides good performance, although better results are obtained when the linear MMSE codes are employed instead of the CDMA ones. |

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.
