METHOD FOR ADAPTIVE QUADRATURE AMPLITUDE MODULATION SIGNAL CONSTELLATION REMAPPING FOR DATA PACKET RETRANSMISSIONS.

摘要

The present invention is related to a simplified QAM signal constellation symbol -wise remapping scheme for data packet retransmissions to improve performance at a high coding rate, wherein mapping rules are determined separately for the I and Q bits The present invention is further related to a method for adaptive switching between bit -wise and symbol -wise constellation remapping for data packet re- transmissions according to channel coding rate to achieve optimum performance across the range of channel coding rates.
