Abstract
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.
