ThèseConception de la couche physique pour la prochaine génération de systèmes de communications sans fil
Multi-user MIMO (multiple-input multiple-output) techniques promise high capacity gains and are currently being implemented in next generation wireless systems. However, a lot of practical issues still remain and need to be solved before making these techniques a success.
This PhD thesis focuses especially on (but is not limited to) practical aspects of MU-MIMO such as practical codebook design, practical receiver implementations, trade-off between feedback and and receiver complexity as well as between feedback and QoS.
The thesis has a strong experimental aspect and will make heavy use of Eurecom's OpenAirInterface platform (www.openairinterface.org). The OpenAirInterface platform is an open-source software defined radio (SDR) development platform targeting 4th generation wireless systems such as LTE and WiMAX (MIMO OFDMA). The platform uses all-IP wireless networking and implements the PHY and MAC layer completely in software and in real-time. A demonstration of the key aspects of the thesis is envisioned at the end of the thesis.
