Claim:
1. A system for providing multiple access communications over a communications link, comprising: an interface for receiving a plurality of data streams from a plurality of data sources; a multiplexor for grouping the plurality of data streams into a plurality of groups; a plurality of orthogonal frequency division multiplexing (OFDM) processing circuitries for applying a same OFDM processing to each of the plurality of groups, wherein each of the plurality of OFDM processing circuitries uses a same combination of frequency and time slot combinations on each of the plurality of groups; a modulator for modulating each of the OFDM processed groups onto a same signal bandwidth by applying a different, unique Hermite-Gaussian function or Laguerre-Gaussian function to each of the OFDM processed groups, each of the different unique Hermite-Gaussian functions or Laguerre-Gaussian functions defined by a respective path passing through coordinates on and between surfaces of a series of a plurality of concentric spheres, each of the spheres defining each of the different orders of Hermite-Gaussian functions or Laguerre-Gaussian functions; a transmitter transmitting modulated OFDM processed groups over the communications link in accordance with each of the different, unique Hermite-Gaussian functions or Laguerre-Gaussian functions; a receiver for receiving the modulated OFDM processed groups over the communications link; a demodulator for demodulating each of the received modulated OFDM processed groups in accordance with the different unique Hermite-Gaussian functions or Laguerre-Gaussian functions for each of the OFDM processed groups; a second multiplexor for separating the plurality of OFDM processed groups into the separate OFDM processed groups; and a second plurality of OFDM processing circuitries for removing the OFDM processing from each of the OFDM processed groups to provide the plurality of data streams as an output.
