I didn't find the article very useful: Things like: "If you use 14 to 3 antenna elements you tend to receive a better S/N of which is based upon all the same output of the transmitter and received receiver." are not very useful to me as I need a solid understanding of the basics.
I would encourage anyone interested in MIMO to read this superbly written document. -- David Mozer IT-Expert on Call Information Technology for Home and Business
