Abstract:
1. A communication system comprising: a plurality of nodes, each for transmitting simultaneously with other nodes a signal unique to that signal's node and representative of at least one non-overlapping sub-channel conveying information derived from a data stream, at least a pair of the nodes having different communication data rate parameters corresponding thereto, each at least one information-conveying non-overlapping sub-channel for each node being different from each information-conveying non-overlapping sub-channel for all other nodes,; and a base station for simultaneously receiving the signals transmitted from each node and processing them to generate, for each information-conveying sub-channel, a signal representative of the information conveyed thereby; wherein at least one of the nodes is for transmitting its signal using multiple sub-channels simultaneously, and in each node, data streams corresponding to sub-channels used in other nodes are set to zero magnitude.
