摘要
A simplified QAM signal constellation symbol-wise remapping scheme for data packet retransmissions to improve performance at a high coding rate. The simplified QAM signal constellation symbol-wise remapping scheme takes advantage of the separate I and Q labeling bits in a QAM signal to reduce the complexity of a receiving node. A method for adaptive switching between bit-wise and symbol-wise constellation remapping for data packet transmissions according to channel coding rate to achieve optimum performance across the range of channel coding rates.
