An adaptive transmit diversity scheme with quadrant phase constraining feedback is proposed in this
paper. With simple linear operations at both transmitter and receiver, the proposed algorithm can achieve better
system performances with only 2M

We present a novel beamforming technique
for multi-user frequency-selective indoor channels called
interference-nulling time-reversal (INTR). The beamformer is
implemented with a pre-filter designed to minimize the interuser
interference pres
