MIMO Hardware Implementation
The Virginia Tech Space- Time Advanced Radio
(VT-STAR) system presents a demonstration of the capabilities of
space-time coding techniques ( [1], [2]). The radio frequency
sub-system is composed of a multi-channel transmitter and receiver
chains implemented in hardware. The capabilities of the MIMO channel
are demonstrated in a Non- Line of Sight (NLOS) indoor environment.
We have developed a wideband, multi-channel,
software-defined measurement receiver (VIPER) to do radio
measurements. [3]. We propose to extend the VIPER test-bed to analyze
MIMO systems.
