Hi all. I'm starting in this subject "Virtual Antenna Arrays" and I'd like somebody to indicate me some good material related to it (books, articles ... ).
TO understand Virtual antenna array, one first needs to know what is the ultimate limit of VAA, i.e., multiple antenna array where transmit antennas can fully cooperate with each other. To this end, I recommand David Tse's excellent book "Fundamentals of Wireless Communications" (you can find it in forum).
Then you can look what happens if you do not allow TX cooperations -- VAA.
