Download or read book Analysis and design of space time block codes for coded MIMO transmissions written by Ammar El Falou and published by . This book was released on 2013 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les systèmes de communication modernes sans fil tels que WiMAX, DVB, WiFi, HSPA+ et 4G ont adopté l'utilisation de plusieurs antennes en émission et en réception. Pour ces systèmes dits Multiple-Input Multiple-Output (MIMO), le codage espace-temps en blocs ou Space Time Block Codes (STBCs) est une technologie prometteuse permettant d'augmenter le débit et la fiabilité des communications sans fil. Les STBCs sont souvent conçus selon des critères asymptotiques, appropriés pour les rapports signal-à-bruit (RSB) élevés. En revanche, les standards définissent l'utilisation du codage MIMO en association avec un codage correcteur d'erreur puissant ou Forward Error Correcting (FEC) comme un turbo code ou un code Low-Density Parity-Check (LDPC) garantissant de faibles taux d'erreurs même pour de faibles RSBs. Dans cette thèse, nous étudions la construction des STBCs pour les systèmes MIMO utilisant un FEC puissant. Dans un premier temps, nous proposons un critère de construction non asymptotique des STBCs, basé sur la maximisation de l'information mutuelle entre les bits émis et reçus, dite Bitwise Mutual Information (BMI). Selon ce critère d'information mutuelle, nous optimisons plusieurs STBCs. Ensuite, nous proposons des STBCs adaptatifs grâce à l'optimisation de leurs paramètres selon le RSB. Les codes proposés conduisent à des performances identiques ou meilleures que les codes du standard WiMAX pour tous les rendements de codage FEC, sans pour autant augmenter la complexité de détection. Parmi eux, le code trace-orthonormal adaptatif proposé permet de passer de manière continue du multiplexage spatial, adapté pour les faibles RSBs et donc pour les rendements de codage faibles, au code d'or, optimal à fort RSB. Les canaux non corrélés, corrélés et une sélection d'antennes à l'émission sont considérés. Nous montrons qu'il est possible de construire des codes STBC adaptatifs également pour ces cas de figure et qu'ils présentent des performances identiques ou meilleures que les codes non adaptatifs. De surcroît, les STBCs classiques sont construits de manière à atteindre la frontière asymptotique du compromis diversité-gain de multiplexage ou Diversity-Multiplexing Tradeoff (DMT). Récemment, un DMT dépendant du RSB ou finite-SNR DMT a été proposé visant à caractériser le DMT selon le RSB. Notre dernière contribution consiste à dériver l'expression exacte du DMT à RSB fini pour les systèmes MIMO ayant deux antennes en émission et/ou en réception. Les canaux de Rayleigh non corrélés et corrélés sont considérés. Pour les RSB opérationnels, nous montrons que les gains de diversité atteints sont largement inférieurs aux valeurs asymptotiques. Ce DMT peut s'avérer être un nouvel outil de grande utilité pour construire des STBCs efficaces pour différentes valeurs de RSBs opérationnels.

Book excerpt: This two-volume book presents an unusually diverse selection of research papers, covering all major topics in the fields of information and communication technologies and related sciences. It provides a wide-angle snapshot of current themes in information and power engineering, pursuing a cross-disciplinary approach to do so. The book gathers revised contributions that were presented at the 2018 International Conference: Sciences of Electronics, Technologies of Information and Telecommunication (SETIT'18), held on 20–22 December 2018 in Hammamet, Tunisia. This eighth installment of the event attracted a wealth of submissions, and the papers presented here were selected by a committee of experts and underwent additional, painstaking revision. Topics covered include: · Information Processing · Human-Machine Interaction · Computer Science · Telecommunications and Networks · Signal Processing · Electronics · Image and Video This broad-scoped approach is becoming increasingly popular in scientific publishing. Its aim is to encourage scholars and professionals to overcome disciplinary barriers, as demanded by current trends in the industry and in the consumer market, which are rapidly leading toward a convergence of data-driven applications, computation, telecommunication, and energy awareness. Given its coverage, the book will benefit graduate students, researchers and practitioners who need to keep up with the latest technological advances.

Download or read book Topics in Audiovisual Translation written by Pilar Orero and published by John Benjamins Publishing. This book was released on 2004-10-20 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: The late twentieth-century transition from a paper-oriented to a media-oriented society has triggered the emergence of Audiovisual Translation as the most dynamic and fastest developing trend within Translation Studies. The growing interest in this area is a clear indication that this discipline is going to set the agenda for the theory, research, training and practice of translation in the twenty-first century. Even so, this remains a largely underdeveloped field and much needs to be done to put Screen Translation, Multimedia Translation or the wider implications of Audiovisual Translation on a par with other fields within Translation Studies. In this light, this collection of essays reflects not only the “state of the art” in the research and teaching of Audiovisual Translation, but also the professionals’ experiences. The different contributions cover issues ranging from reflections on professional activities, to theory, the impact of ideology on Audiovisual Translation, and the practices of teaching and researching this new and challenging discipline.In expanding further the ground covered by the John Benjamins’ book (Multi)Media Translation (2001), this book seeks to provide readers with a deeper insight into some of the specific concepts, problems, aims and terminology of Audiovisual Translation, and, by this token, to make these specificities emerge from within the wider nexus of Translation Studies, Film Studies and Media Studies. In a quickly developing technical audiovisual world, Audiovisual Translation Studies is set to become the academic field that will address the complex cultural issues of a pervasively media-oriented society.

Download or read book Signal Processing for Communications written by Paolo Prandoni and published by Collection Savoir suisse. This book was released on 2008-06-17 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: With a novel, less classical approach to the subject, the authors have written a book with the conviction that signal processing should be taught to be fun. The treatment is therefore less focused on the mathematics and more on the conceptual aspects, the idea being to allow the readers to think about the subject at a higher conceptual level, thus building the foundations for more advanced topics. The book remains an engineering text, with the goal of helping students solve real-world problems. In this vein, the last chapter pulls together the individual topics as discussed throughout the book into an in-depth look at the development of an end-to-end communication system, namely, a modem for communicating digital information over an analog channel.
