Claim:
An interference suppression orthogonal frequency division multiplexed system, comprising: an interference suppression orthogonal frequency division multiplexed transmitter, wherein the interference suppression orthogonal frequency division multiplexed transmitter comprises: a serial-to-parallel converter, the serial-to-parallel converter for accepting an input data stream and for operating on the input data stream to produce a plurality of parallel data streams; a plurality of spreaders, each spreader of the plurality of spreaders coupled to the serial-to-parallel converter, each spreader of the plurality of spreaders operates by applying an orthogonal binary code sequence to one of the plurality of parallel data streams spreading the one of the plurality of parallel data streams resulting in a set of parallel spread data streams, wherein each one of the set of parallel spread data streams comprises a plurality of sub-carriers, wherein each one of the plurality of sub-carriers contains all data bits of the input data stream separated from each other by the orthogonal binary code sequence where a power of each one of the data bits is spread to all of the plurality of sub-carriers; and a plurality of serial-to-parallel buffer and encoder devices, each of the plurality of serial-to-parallel buffer and encoder devices coupled to one of the plurality of spreaders, each of the plurality of serial-to-parallel buffer and encoder devices is for accepting one of the set of parallel spread data streams and for operating on the one of the set of parallel spread data streams to produce a plurality of parallel sub-streams.
