A throughput expansion method (10) for effectively increasing the throughput of a transmission medium (42). The transmission medium (42), which may be an available frequency spectrum (12) as of a telephone wire, is divided into a plurality of physical channels (16) and a data stream (20) is parsed into a plurality of virtual channels (22). The virtual channels (22) are multiplexed onto the physical channels (16) such that each of the virtual channels (22) will have a unique set of the physical channels (16) although each of the physical channels (16) will have data pertaining to more than one of the virtual channels (22) multiplexed thereonto. The physical channels (16) are communicated from an encoder (38) to a receiver (40) via the carrier (22) and the receiver (40) reconstructs the virtual channels (22) by separately summing the physical channels (16) which make up the virtual channels (22). In each such summation information that is common to all of a set of the physical channels (16) will be emphasized as the data of the receptive virtual channel (22) and other content of such physical channels (16) will tend to be self canceling. |
