摘要：Methods and systems for communicating on a wireless channel are providedwhich enable subscribers that share the channel to transmit using different modulationschemes. The modulation scheme used by each subscriber is assigned to the subscriber
by a wireless access termination system. The modulation scheme assigned to a subscriberby the wireless access termination system is determined based on measurements of thequality of signals received from that subscriber. In one embodiment, the inventionincludes a transmitter and a receiver. The receiver is capable of transmitting data usingone of a number of encoding and symbol constellation configurations. The receiver isalso capable of receiving a first signal. Receiving the first signal causes the transmitter totransmit a second signal using a specified encoding and symbol constellationconfiguration.
