A method for multiple users accessing a common channel in which coded application bits are generated and transmitted for a plurality of applicatio ns for a plurality of users. A plurality of tones are assigned to the coded applicati on bits for each application. The coded application bits for each application are encoded int o 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 transm ission on a common channel. At a receiver, the multitone symbols for each application ar e 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 b its. The coded application bits are then decoded for each application.
