Combined array processing and space-time coding

The information capacity of wireless communication systems may be increased by employing multiple transmit and receiver antennas. The goal of the system design is to exploit this capacity in a practical way. To increase data rate over wireless channels, space-time coding techniques appropriate to multiple transmit antennas are employed. These space-time codes introduce temporal and spatial correlation into signals transmitted from different antennas to provide diversity at the receiver, and coding gain over the uncoded system. The encoding and decoding complexity are reduced by partitioning the antennas at the transmitter into small groups, and using individual space-time code, called component codes, to transmit information from each group of antennas.
