We present a novel spread spectrum communication system for the secure transmission of digital information. The approach is based on the unconventional self-encoding principles that we have developed at the University of Nebraska for the modulation and detection of spread spectrum signals. The proposed system does not use pseudo-random codes, and is unique in that traditional transmit and receive code generators based on maximal-length sequences or chaotic signals are not needed. In fact, the enhanced transmission security arises not only due to the spread-spectrum nature of the signal, but also from the true randomness of the unique spectrum spreading and de-spreading processes. This paper describes the proposed system and presents the theoretical and simulation results of the system performance in an additive white Gaussian noise channel.
