Channel models and algorithms for massive MIMO

Abstract: Massive MIMO has drawn great attention in the past years, as it promises a dramatic increase in the capacity of multi-user systems, while at the same time simplifying receiver algorithms. However, there are also significant practical challenger, like the cost related to a massive number of RF chains, so that ingenious new algorithms are required for retaining performance while keeping complexity under control. Many of the algorithms are analysed with very simplified channel models, and it is not immediately obvious whether performance can be retained in more realistic settings. The current talk will first give an overview of channel measurements and modelling specifically for the massive MIMO scenarios. We will then describe a simplified algorithm, called JSDM, that is based on RF pre-processing, and analyse how realistic propagation conditions impact its performance, and how it can be modified to adapt to such conditions.
