Full textIn this thesis, we study the resource allocation problem within the framework of 4G LTE networks. The OFDMA access method divides the radio resources both in the frequency and time domains. Due to channel impairments, users do not always have the same transmit/receive rates on each resource. In this context, our problem is to share the radio resources between users and enable them to transmit/receive data. The algorithm used to allocate resources is of fundamental importance on system performance. The LTE standard adds constraints to this problem and makes harder the exploitation of the frequency and the multi-user diversity. Indeed, under these constraints, we show that the resource allocation problem becomes part of the « most difficult » problems. Therefore, the conventional algorithms are often not adapted to a real LTE network. We provide resource allocation algorithms for both the uplink and downlink of LTE. The constraints of the standard are rigorously taken into account in order to build effective solutions. In addition, the proposed algorithms are generic and can adapt to a wide variety of objectives. In particular, we focus on the support of multimedia traffic with heterogeneous quality of service requirements (bit error rate, delay, jitter, etc.). Indeed, the gradual increase of the offered throughput and the strong popularity of smart mobile devices lead to a massive use of multimedia applications. Our algorithms are validated through extensive simulation. By this means, we show that the inclusion of LTE constraints is essential to achieving high performance

Full textThis thesis concerns the study, the realisation and characterisation of an antenna array fed and steered by an optical command. The array is fed by "true time delays". Three systems are proposed. The first one works at 960 MHz and allows to validate the control of the array pointing direction by tuning the optical wavelength that carries the microwave signal. The second antenna presents a wide bandwidth around 2 GHz (25%) and demonstrates that the pointing direction of the array remains invariant with the emitted frequency. The last studied corresponds to the conception and to the realisation of a prototype working in the millimetre-wave domain. It is based on the previous system used at low frequency, to create the delays, which is associated to microwave mixing to produced out of phase millimetre-waves. The interest of this system is to obtain a wide bandwidth control of the pointing direction and to simplify the feed circuit of the radiating elements

Full textWireless underground sensor networks (WUSN) consist of sensors which are buried in a medium with their antennas, in particular in soil. They attract a huge interest in different fields, like environment monitoring, precise agriculture, navigation and security. The existing narrowband systems operate at frequencies below 1 GHz. These systems imply the use of cumbersome antennas, which complicates the deployment and increases its cost. Furthermore, the use of narrow bandwidths limits the possible communication data rates and the potential resolution in localization applications. Finally, current systems are very energy consuming, which limits the lifetime of the underground elements.To overcome these drawbacks for certain applications of WUSN, we propose in this thesis the use of ultra wideband technology (UWB), in the normalized band 3.1 - 10.6 GHz, in WUSN. This technique allows the use of compact antennas, simplifying deployment, improving the localization accuracy and increasing communication data rates and the lifetime of the underground sensors.In order to assess the feasibility study of UWB WUSN, we have designed and realized three compact UWB antennas and analyzed the effect of soil on the performances of these underground UWB antennas and on the underground UWB communication links. Compared with operating in free space, burying the antenna shifts the antenna bandwidth towards low frequencies. This shift increases with soil water content. The attenuation introduced by the buried UWB channel, increases with the operating frequency, the burial depth and the soil moisture. However, we have shown that reliable communications are possible for distances of propagation in soil smaller than 30 cm and soil water contents below 20%

Full textThis PhD thesis is dedicated to the study of Electromagnetic Band Gap antennas based on metasurfaces. Metasurfaces are employed in the antenna design to correct the usual limitations of the technology and more precisely to enlarge the banwidth. The possibilities offered by combining partially reflecting surfaces, with respect to structure height are explored. Multi-band and broadband EBG antennas with structured interface are designed. An experimental validation of the wideband antenna concept based on metasurfaces is realized. Finally, it is demonstrated that the product gain-bandwidth of such an antenna can be further improved by the use of a multiple feeding sources system
