Abstract
Use of multiple antennas at the transmitter and the receiver to increase the information capacity has received considerable attention. To exploit the capability of such systems in a practical way, it is of interest to ask if there are good codes with reasonable decoding complexity. Another question of interest is the simplicity of design. This issue is particularly important in the case where the number of antennas in transmitter and receiver are large and a space-time code may be to complex to design and decode. We illustrate a class of codes which are simpler to design and the interference across antennas is suppressed by linear processing at the receiver. The performance of such codes is excellent and much better than the group interference suppression techniques employed in conjunction with the space-time codes. Use of error detection schemes is shown to further improve the performance without much change in the design of codes and decoding complexity.
