Securing OFDM over Wireless Time-Varying Channels Using Subcarrier Overloading with Joint Signal Constellations
<p/> <p>A method of overloading subcarriers by multiple transmitters to secure OFDM in wireless time-varying channels is proposed and analyzed. The method is based on reverse piloting, superposition modulation, and joint decoding. It makes use of channel randomness, reciprocity, and fast...
