Abstract
A communications system comprises first signal processing circuitry for receiving a plurality of input data streams and applying a different orthogonal function to each of the plurality of input data streams. Second signal processing circuitry processes each of the plurality of input data streams having the different orthogonal function applied thereto to multiplex a first group of the plurality of input data streams having a first group of orthogonal functions applied thereto onto a carrier signal and to multiplex a second group of the plurality of input data streams having a second group of orthogonal functions applied thereto onto the carrier signal. A MIMO transmitter transmits the carrier signal including the first group of the plurality of input data streams having the first group of orthogonal functions applied thereto and the second group of the plurality of input data streams having the second group of orthogonal functions applied thereto over a plurality of separate communications links. Each of the plurality of separate communications links go from one transmitting antenna of a plurality of transmitting antennas to each of a plurality of receiving antennas at a MIMO rece…
