Nouvelles méthodes de traitement d’antenne en émission alliant diversité et formation de voie (2006)
Abstract / truncated to 115 words
This work deals with the use of an antenna array at the base station of a mobile communication system for transmission. In reception, solutions that exploit the antenna array are now well established. In transmission, however, the problem remains open. Two approaches are possible : exploit the array by using beamforming techniques or by using diversity techniques. These two approaches are based on opposite assumptions about the channels correlation, which implies a greater or smaller distance between antennas, depending on the environment. In practice, these assumptions are not verified. Here, we aim to deal with the problem as a whole for better exploiting the antenna array. This work treats the mono-user case, as well as ... toggle 10 keywordsbeamforming – diversity – wireless – mimo – smart antennas – minimum ber – formation de voie – diversité – communications sans fils – multi-user
