ECHNOLOGICAL PROSPECTS AND SOCIAL APPLICATIONS SET Coordinated by Bruno Salgues There are many controversies with respect to health crisis management: the search for information on symptoms, misinformation on emerging treatments, massive use of collaborative tools by healthcare professionals, deployment of applications for tracking infected patients. The Covid-19 crisis is a relevant example about the need for research in digital communications in order to understand current health info communication. After an overview of the challenges of digital healthcare, this book offers a critical look at the organizational and professional limits of ICT uses for patients, their caregivers and healthcare professionals. It analyzes the links between ICT and ethics of care, where health communication is part of a global, humanistic and emancipating care for patients and caregivers. It presents new digitized means of communicating health knowledge that reveal, thanks to the Internet, a competition between biomedical expert knowledge and experiential secular knowledge.

This text provides an introduction to the analysis and design of digital communication systems. The third edition has been updated with a discussion of modern technological advances, providing coverage of such topics as digital modulation and demodulation techniques, source coding, channel coding and decoding, spread spectrum signals, channel equilization, multiuser communications, and modulation and coding for fading multipath channels. In addition, the book has been reorganized so that each chapter builds on previous material, begins with an introduction to the history and classification of channel models and reviews important topics in probability and stochastic processes.

En quelques années, les organisations publiques et privées ont imposé à leurs salariés une grande conversion numérique au nom de la performance économique et de l’optimisation des ressources et des moyens. Ce diktat technologique a été massivement plébiscité par les individus eux-mêmes qui ont volontairement intégré ce processus de numérisation à leurs activités personnelles, socialisantes et ludiques. Malgré les études menées ces dernières années en sciences humaines et sociales, confirmant la persistance de fossés numériques, l’émergence de situations de non-usages volontaires et le risque d’avènement d’une société du contrôle, la transformation numérique sociétale apparaît réellement irréversible. Ce nouvel ordre numérique engendre de nouvelles recompositions en matière de communication et de gouvernance au sein des organisations, des changements radicaux dans les relations sociales, des logiques de flux, d’instantanéité, d’immédiateté et d’interopérabilité, etc., et s’avère d’une grande richesse pour la Recherche en Sciences Humaines qui découvre dans cet univers numérique, de nouveaux objets d’étude que cet ouvrage invite à découvrir.

It is a complete training in digital communications in the same book with all the aspects involved in such training: courses, tutorials with many typical problems targeted with detailed solutions, practical work concretely illustrating various aspects of technical implementation implemented. It breaks down into three parts. The Theory of information itself, which concerns both the sources of information and the channels of its transmission, taking into account the errors they introduce in the transmission of information and the means of protect by the use of appropriate coding methods. Then for the technical aspects of transmission, first the baseband transmission is presented with the important concept and fundamental technique of equalization. The performance evaluation in terms of probability of errors is systematically developed and detailed as well as the online codes used. Finally, the third part presents the Transmissions with digital modulation of carriers used in radio transmissions but also on electric cables. A second important aspect in learning a learner's knowledge and skills is this book. It concerns the "Directed Work" aspect of a training. This is an ordered set of 33 typical problems with detailed solutions covering the different parts of the course with practical work. Finally, the last aspect concerns the practical aspects in the proper sense of the term, an essential complement to training going as far as know-how. We propose here a set of 5 practical works.
