Abstract

In the past decades, multiple antenna systems were widely employed in modern wireless network to improve the communication performance. For example, iPhone XS is equipped with six antennas and Nokia 5G AirScale has up to sixty-four antennas. How multiple input multiple output (MIMO) technique boosts both the channel capacity and link reliability simultaneously? In this reading group sharing, I will discuss the theoretical foundation of MIMO setup by Emre Telatar at the end of 20th century and a powerful statistical tool, Wishart distribution, to analyze MIMO performance. Then I will go through its development from early days point-to-point MIMO to today’s massive MIMO. We can discover how MIMO overcomes the challenges along the way of bringing theoretical analysis into current real applications.
