ABSTRACT Ample amount of research has been done for analysing nonlinear phenomenon in power electronics converters. Application of chaotic power electronics converters in spread spectrum communication in recent times is catching interest. This paper proposes a methodology for using chaotic current mode‐controlled DC (Direct Current)–DC (Direct Current) boost converter in spread spectrum communication. A noncoherent receiver is developed. For this, an Adaline‐based adaptive filter is designed to recover the message from spread spectrum signal at the receiver end. The proposed Adaline‐based receiver is tested by transmitting various types of message signals while considering white noise at different signal‐to‐noise ratio. For designing noncoherent receiver‐based chaotic communication, use of power electronics converters is expected to play a vital role in the future. Copyright © 2012 John Wiley & Sons, Ltd.
