Comparison of MIMO channels from multipath parameter extraction and direct channel measurements [PDF]
, 2004 This work presents a MIMO throughput performance analysis of dynamic wideband double-directional channel measurements that were recently obtained by the University of Bristol. Identical 16-element uniform circular arrays (UCAs) were employed at both ends

Synchronisation Issues in Non-coherent MIMO Systems
In this article, we identify some of the key problems that may be encountered when designing Non-Coherent (NC) Multiple-Input Multiple-Output (MIMO) DownLink (DL) synchronisation schemes for communicating over multi-path fading channels.
