| Abstract | Cet article présente des stratégies de codage permettant d’implanter Vidée du codage avec information adjacente (ou dpc, dirty paper coding) dans le cadre du canal de diffusion avec un émetteur et des récepteurs à antennes multiples. Ce travail décrit des stratégies de codage qui utilisent la connaissance du canal à l’émetteur qui s’inspirent de concepts suggérés par la théorie de l’information. La mise en œuvre complète des algorithmes de codage et de décodage nous permet d’évaluer les performances de ces stratégies en termes de taux d’erreurs binaires et non pas en terme de région de débit de codage. Différents codeurs internes et externes sont comparés entre eux. Enfin, nous considérons le codage dpc en tant que stratégie d’accès multiple et le comparons avec l’accès multiple temporel (TDMA). Nous verrons que les résultats obtenus pour les codeurs pratiques proposés ne concordent pas toujours avec les prédictions théoriques pour les codeurs optimaux.We propose several dirty paper coding schemes for the broadcast channel when both the transmitter and receivers are equipped with multiple antennas. These schemes are based on channel state information at the transmitter and inspired from information-theoretic concepts. The proposed end-to-end algorithms allows us to evaluate the performance of the broadcast channel in terms of bit error rates and not in terms of coding rates as it is usually the case in the literature. Different inner coding schemes such as the ZF-DPC and MMSE-DPC and different outer coding schemes such as the THS, SCS and TCQ are compared and discussed. We also consider the DPC idea as a way of implementing a multiple access scheme. In this respect it is compared with the well-known TDMA scheme. Sometimes our conclusions show quite surprising results in comparison to what is expected by pure information-theoretic considerations. |

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.
