Claim 0:
1. A communications system, comprising:
mode division multiplexing circuitry for receiving a plurality of input data streams, applying a different orthogonal function to each of the plurality of input data streams, and multiplexing a first group of the plurality of input data streams having a first group of orthogonal functions applied thereto onto a carrier signal and a second group of the plurality of input data streams having a second group of orthogonal functions applied thereto onto the carrier signal to provide a mode division multiplexed carrier signal;
a maximum ratio combining (MRC) circuit for processing the mode division multiplexed carrier signal using maximum ration combining to improve signal to noise ratio; and
a MIMO transmitter for transmitting the MRC processed mode division multiplexed 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 from the MIMO transmitter, each of the plurality of separate communications links from one transmitting antenna of a plurality of transmitting antennas to each of a plurality of receiving antennas at a MIMO receiver, wherein the MIMO transmitter transmits the MRC processed mode division multiplexed carrier signal including the first and the second groups of the plurality of input data streams using a channel matrix of an impulse response of a channel, the channel matrix is created using a pilot signal transmitted on a pilot channel.
