Method for multitone division multiple access communications

Abstract From the Canadian patent

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 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 …
