The bit rate at which a digital wireless communications system communicates
data in scattering environments may be significantly increased by using
multiple antennas at both the transmitter and receiver and by decomposing
the channel into m subchannels. In the same frequency band, m one
dimensional signals are transmitted into a scattering environment which
makes these transmitted signals appear spatially independent at the
receiver antenna array. The high bit rate is enabled by special receiver
processing to maximize the minimum signal-to-noise ratio of the receiver
detection process.
