Beam Forming vs Diversity

 http://users.soe.ucsc.edu/~friedlan/TXDIVBF.PDF

The only difference between transmit and receive diversity
is that, when Channel State Information (CSI) is not available at
the transmitter, then array gain is not possible to obtain, whereas
array gain is possible to obtain in the receive diversity system, as we
assume that perfect CSI is always available at the receiver .
