We propose an antenna grouping method that
improves the error rate performance of space-time codes in
a wide range of mobility environments. The idea is to group
symbols to antennas based on limited feedback from the receiver.
Our approach requires only two-bits of feedback information
to achieve near full diversity and full rate for a four transmit
antenna system. Numerical results illustrate the bit/frame error
gain over antenna subset selection.
