Claim 10:
11. A communications system, comprising:
mode division multiplexing circuitry for receiving a plurality of input data streams and generating a first group of the plurality of input data streams having a first group of orthogonal functions applied thereto and a second group of the plurality of input data streams having a second group of orthogonal functions applied thereto onto a mode division multiplexed carrier signal;
a maximum ratio combining (MRC) circuit for receiving the mode division multiplexed carrier signal and 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 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.
