Constant-rate Adaptive Space-Time Code Selection Technique for Wireless Communications

constant-rate space-time code selection technique for transmit antenna diversity systems is proposed. The proposed technique selects both the space-time code and the number of transmitter antennas through a comparison of equivalent SISO channels with a set of predetermined threshold levels, using only four bits for feedback. The constant-rate transmission is based in the inclusion of a complementary transmission mode, which is used whenever no equivalent SISO channel's envelope is found to be over the threshold levels.
