ABSTRACT:
A method for multiple users accessing a common channel in which coded application bits are generated and transmitted for a plurality of applications for a plurality of users. A plurality of tones are assigned to the coded application bits for each application. The coded application bits for each application are encoded into multitone symbols at a transmitter using the plurality of tones assigned to the coded application bits. The multitone symbols for each application are synchronized for transmission on a common uplink channel. At a receiver, the multitone symbols for each application are received from the common channel and tone decoded into the coded application bits for each application using the plurality of tones assigned to the coded application bits. The coded application bits are then decoded for each application.
