La recrudescence et le déploiement de nouveaux services et applications dans les systèmes de communication, ainsi que le nombre toujours croissant d'utilisateurs, conduisent à une augmentation de la consommation d'énergie des réseaux et technologies de l'information et de la communication, ce qui contribue de façon significative au réchauffement climatique. Ainsi, pour satisfaire aux exigences énergétiques aussi bien pour les réseaux sans fil que filaires, de nouvelles approches doivent être développées. Dans un premier temps, nos travaux de recherche se focalisent sur les mécanismes d'allocation des ressources de systèmes point-à-point dans deux modes de transmission (mono-porteuse et multi-porteuses) avec pour objectif la minimisation de l'énergie consommée. Dans cette partie, nous présentons une nouvelle approche appelée ultra large bande (ULT) ainsi qu'un nouvelle métrique pour les systèmes de communication. En se basant sur cette nouvelle approche, des algorithmes d'allocation des ressources sont proposés afin d'améliorer l'efficacité énergétique des réseaux sans fil et des réseaux filaires, dont notamment les réseaux CPL (courant porteur en ligne).Dans un second temps, nous étudions les techniques impulsionnelles ultra large bande (ULB). Un simulateur logiciel de laisoon point-à-point ULB impulsionnelle, générique et paramétrable a été développé. L'objectif est d'améliorer l'efficacité énergétique d'une laison ULB. les différents paramètres du systèmes (largeur de l'impulsion, temps de garde, nombre d'impulsions transmises) sont exploités afin d'optimiser les performances du système.

Green communication has emerged as one of the most important research topics for radio systems. This leads us to develop an energy-efficient mechanism which adjusts transmission power according to the traffic load and reduces the energy per bit usage. For the vision of Europe 2020 as a smart, sustainable and inclusive economy to become reality, the EU have set forth the 20:20:20 targets by which greenhouse gas emissions and energy reduction of primary use should be reduced by 20% while 20% of energy consumption should come from renewable resources. In fact, in today's energy-conscious society, Information and Communication Technology (ICT) accounts for 2% of the global CO2 emissions. A medium-sized cellular network uses as much energy as 170,000 homes, while the cost of powering the existing BSs accounts for a staggering 50% of a service provider's overall expenses. Therefore, new solutions are required whereby operators can accommodate additional traffic volume whilst reducing their investment in new infrastructure and beyond that significantly reduces their energy bill. Moreover, the EU political agenda, in unison with expected growth in mobile data, has identified cost and energy per bit reduction as a stringent design requirement for mobile networks of the future. Green Communication for 4G Wireless Systems mainly covers energy efficient techniques in physical, MAC and network layers. Cross-layer energy efficiency optimization in time and frequency has been also discussed with two fundamental tradeoffs, energy efficiency and spectral efficiency. This technical introduction to Green Communication in 4G wireless systems, explaining the rather complex standards (3GPP Releases R10 and R11), is a must-read for engineers, decision-makers and students interested in Green Communication, as well as other researchers and scientists from this evolving field.

Space-time coding techniques play a major role in modern wireless communication systems since they can achieve very high data transmission rates. Designing efficient algorithms to implement these techniques is a significant challenge, and there is currently a great amount of interest in sphere decoding algorithms in this context. This book will describe efficient algorithms for detection and decoding, focussing on receivers in wireless communication systems. The complexity and design of sphere decoding algorithms will be discussed in detail, and their performance analyzed. The book is aimed at researchers and graduate students of electrical engineering and computer science. It will also appeal to practitioners in the wireless industry.
