about "MIMO"
I want to know something about "MIMO".
Do anybody have fundamental infromation about "MIMO"?
If you have, please mail to me
Thanks a lot.

This is a fancy name for a decades old technology. It is a phased array antenna with multiple beams and one output per beam so that several transmitters can be received at the same time.
mimo essentially means having multiple antennas at both end of commnications link. these help you to combat small scale fading and involve impressive capacity gains. there is a paper by gans which is widely refered too. just google on mimo you will get tons of stuff to read. there is a also a book by paulraj(stanford professor) if you are interested.

I hope to have information about MIMO as well.....thanks.
Multiple-Input Multiple-Output (MIMO) wireless systems represent an economical way to increase user capacity in a variety of environments. The use of antennas at both transmitter and receiver allows
Multiplicative increase in capacity and spectral efficiency
Dramatic reductions of fading thanks to diversity
Increased system capacity (number of users)
Lower probability of detection
Improved resistance to interference
what's the relation between MIMO and the IEEE 802.11n Wireless System ? .. and what's the use of it in this very system ?
Hi,
You ca go thru below link and I am also attaching one PDF document which will give u good idea about MIMO.

Contrary to what may be reported, MIMO is *not* antenna diversity, beam forming etc. There are many pseudo-MIMO products out there in WLAN but not a real MIMO yet.
MIMO takes advantage of fading. It doesn't try to 'fix' it. A 2x2 MIMO system for example outputs different data at the same frequency (one data stream for each antenna) which is coded in such a way so that at the receiver the fading is used to merge and decode the data successfully.
Read the following:

Contain Infotmation theory and communication theory point of view of the MIMO systems. Very well written book.

very good. most of the students and engineers think that MIMO systems operate as smart antennas. MIMO takes advatntage of fading but smart antanna are design to combat it.
