Increased capacity: Space-time coding can be used to increase the capacity of a wireless link by transmitting multiple data streams simultaneously. This is possible because space-time coding uses the multiple antennas in a MIMO (Multiple-Input Multiple-Output) system to transmit different data streams on different antennas.
Improved reliability: Space-time coding can also be used to improve the reliability of a wireless link. This is because space-time coding can be used to transmit the same data stream on multiple antennas. If one of the antennas experiences fading, the receiver can still receive the data from the other antennas.
Reduced transmit power: Space-time coding can also be used to reduce the transmit power required for a given data rate. This is because space-time coding can be used to increase the signal-to-noise ratio (SNR) at the receiver. This means that the transmitter can use less power to achieve the same data rate.
