Abstract
We address the problem of transmitting multiple cochannel signals
from an antenna array to several receivers so that each receiver gets
its intended signal with minimum crosstalk from the remaining signals.
In addition to the usual “information” mode, we propose a
“probing” mode during which probing signals received at the
mobiles are fed back to the transmitter. These probing signals are used
to identify an unknown propagation environment, enabling the transmitter
to form the necessary transmission beampatterns
