1. A method for transmitting a pilot signal, comprising:

  • generating the pilot signal at a transmitting unit;

    modulating the pilot signal using quantum level overlay modulation to apply at least one orthogonal function to the pilot signal, wherein the modulated pilot signal is mutually orthogonal in both time and frequency domains, further wherein the modulated pilot signal minimizes time-frequency resources;

    transmitting the modulated pilot signal from the transmitting unit to a receiving unit over a pilot channel; and

    wherein the at least one orthogonal function applied to the pilot signal substantially reduces pilot channel contamination on the pilot channel from other pilot channels.
