In this paper we propose a chaotic frequency modulation (CFM) technique for spread spectrum communications. Existence and stability of the synchronous mode is demonstrated analytically and numerically. Unlike synchronization of two conventional chaotic oscillators via an FM channel, the proposed method provides selectivity with respect to interference within the frequency range of chaotic frequency oscillations. This method provides a viable alternative to a recently proposed ‘interpolated’ frequency hopping for spread‐spectrum communication systems. Copyright © 1999 John Wiley & Sons, Ltd.
