A packet radio system is provided with a multiple access scheme which operates to schedule transmissions of data bearing radio packets on a common communications channel from a plurality of users to a common receiver of the said system. The radio packets via which the plurality of users communicate include synchronization data, and by providing the common receiver with a multi-user detector, contemporaneously transmitted packets may be detected and recovered in dependence upon the synchronization data, thereby substantially increasing a throughput of the packet radio system.

[ What is claimed is:] [1.] A packet radio system, comprising a multiple access scheme which operates to schedule transmissions of data bearing radio packets on a common communications channel from a plurality of a users to a common receiver of said system, wherein:said radio packets include synchronization data and are arranged to be modulated in accordance with a trellis coded modulation scheme;said common receiver includes a multi-user detector which operates to detect and recover contemporaneously transmitted packets in dependence upon said synchronization data, thereby substantially increasing a throughput of said packet radio system; andradio packets which are contemporaneously transmitted on said common communications channel are arranged to be re-transmitted with substantially different synchronization data and are arranged to be modulated with substantially different trellis codes.
