Cryptographic Spread Spectrum Relay Communication

Spread spectrum (SS) is a technique of secure communication, which increases resistance to natural interference and jamming, and prevents detection. If a cryptographically secure pseudo random sequence is used, the communication becomes more secure. Generally some short pseudo-random sequences are used in Spread spectrum. In this paper we present comparatively a different technique of signal hiding where we use a non secret communication and a secret Spread spectrum communication. We present a class of relay channel with orthogonal components for transmission of our proposed SS communication.
