MIMO Channel Capacity and Configuration Selection for Switched Parasitic Antennas

ETRI Journal, 2018
Multiple‐input multiple‐output (MIMO) systems offer significant enhancements in terms of their data rate and channel capacity compared to traditional systems. However, correlation degrades the system performance and imposes practical limits on the number

Comparison of precoding methods for broadband MIMO systems

, 2009
In this paper we investigate non-linear precoding solutions for the problem of broadband multiple-input multipleoutput (MIMO) systems. Based on a broadband singular value decomposition (BSVD) we can decouple a broadband MIMO channel into independent ...
