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.

LMI-based Controller Design for Leaky-integrator MIMO Systems
Applications of Modelling and SimulationLeaky-integrator systems have attracted attention due to their capability of capturing the gradual loss of the system states. Thanks to the advantages of taking into consideration the leaky effect on gradual loss of systems states, leaky-integrator ...

High-performance WLAN architectures using MIMO technology in Line-of-Sight [PDF]
, 2006 This paper investigates the Packet-Error-Rate (PER) and throughput performance of WLANs in Line-of-Sight (LoS) conditions. A novel antenna array architecture is proposed as a way of overcoming the problem of excessive correlation under these conditions ...

Widely linear filtering in modern MIMO transceivers [PDF]
, 2009 This thesis deals with the multiple-input multiple-output (MIMO) equalization with widely linear (WL) filtering. The WL filtering outperforms the linear one in presence of rotationally variant signals, with no significant complexity increase. It has been
