Being the manner which chooses the signal constellation for adaptation quadrature amplitude modulation constellation

摘要

The present invention relates to the re-mapped symbol unit of the QAM signal constellation, which is simplified in order to improve the performance of a high coding rate for data packet retransmission, map rules to the Q-bit I and is determined separately. Furthermore, to achieve optimum performance over a range of channel coding rate, due to the channel coding rate, the present invention constellation remapping symbol unit and constellation remapping in bits for the data packet retransmission relates to a method for adaptive switching between.
