Abstract:

Massive MIMO has generated an enormous interest due to its many potential benefits. In this talk, Massive MIMO will be introduced followed by an overview of some key results about achievable rate, energy efficiency and transmit/receive processing. Also, some challenges related to estimation of Channel State Information (CSI) and Radio-Frequency (RF) impairments will be presented. After this overview, the characteristics of the propagation channel and the effects of phase noise will be examined in more detail, showing some recent results. Finally, some ideas for a non-coherent massive MIMO scheme will be discussed.
