One of my reseach topics: MIMO Channel Estimation

The importance of wireless channel estimation and understanding channel knowledge for successful design of communication systems can never be overstated. In eariler of channel estimation, the wireless medium was viewed as an obstacle or challenge in designing reliable communication links. However, decades of research and subsequent insights have change this paradigm. Modern day communcation systems rather tend to exploit the channel knowledge for increasing system reliablity and thoughtput by employing techniques such as MIMO, which is the key for extending the limits of existing communication systems. Thus, MIMO channel estimation become a most important challenge because it must be to overcome the highly frequency selective of the fading channel.

Hello there! I could have sworn I've been to this site before but after looking at a few of the articles I realized it's new to me.
Anyhow, I'm certainly happy I found it and I'll be bookmarking it and checking back frequently!
