Proposal of channel synthesized modulation for secured access on physical layer

This paper proposes a novel technique to achieve secured access on the physical layer. This technique - the channel synthesized modulation - is designed to combine the channel parameters with a modulation signal to synthesize a signal on the receiving position through the channel between both terminals. The channel is formed uniquely by the terminals´ position and their physical layout, and it is identical at both points. The channel parameters analyzed from the received signal are treated as unidentified information by the third terminal. Therefore this signal can be demodulated by the specific terminal. This paper describes a new modulation concept and its principles, shows some simulation results and its possibilities. A simulation is carried out using static and AWGN (additive white Gaussian noise) condition. Finally the secured access technique is introduced as an application.
