Systems and methods for communicating using ASK or QAM with constellation points having different distances

摘要

Systems and methods of performing ASK or QAM modulation with uneven distance between symbols are provided (d i ,µ i d i ,d q ,µ q d q ). Different bit positions mapped to such symbols are assigned to different receivers, with the result that there are different BER performances among bits sent from a transmitter to the different receivers.
