Patent ID: 7317750

Claim:
A multi-carrier communications transmitter including: a sub-carrier allocator adapted to allocate at least one set of subcarriers for communication, a pulse generator to be coupled to the sub-carrier allocator, the pulse generator adapted to generate a plurality of pulses having spectral components corresponding to the at least one set of subcarriers, wherein the pulse generator comprises: a subcarrier weighting module to impress at least one set of complex weights generated from at least one carrier interferometry code onto the at least one set of subcarriers to generate a plurality of weighted subcarriers; and a sub-carrier combiner adapted to combine the weighted subcarriers to produce the plurality of pulses; a modulator to be coupled to at least one of the sub-carrier allocator and the pulse generator, the modulator adapted to impress at least one data symbol onto the plurality of pulses, and a sequential pulse positioner to be coupled to at least one of the sub-carrier allocator, the pulse generator, and the modulator, the sequential pulse positioner to sequentially position the plurality of pulses.
