Abstract-- We investigate robust wireless communication in
high-scattering propagation environments using multi-element
antenna arrays (MEA's) at both transmit and receive sites. A
simplified, but highly spectrally efficient space­time communi-
cation processing method is presented. The user's bit stream is
mapped to a vector of independently modulated equal bit-rate
signal components that are simultaneously transmitted in the
same band. A detection algorithm similar to multiuser detection
is employed to detect the signal components in white Gaussian
noise (WGN). For a large number of antennas, a more efficient
architecture can offer no more than about 40% more capacity
than the simple architecture presented. A testbed that is now
being completed operates at 1.9 GHz with up to 16 quadrature
amplitude modulation (QAM) transmitters and 16 receive anten-
nas. Under ideal operation at 18 dB signal-to-noise ratio (SNR),
