Software Defined Radio Implementation of Generalized Chaotic Generator

In this paper, we present a generalized model for chaos generation using software defined radio. This model allows generating chaotic signals such as: Lorenz, Chen and Lu. We have used Software Defined Radio (SDR) to implement this generalized model using GNURadio. A new chaos block has been created and added to GNURadio-Companion (GRC) to be used as a signal source making this generator suitable for secure real-time transmissions. An experimental validation is carried out using SDRs hardware to show the effectiveness of this new block. The aim of this implementation is to use this chaotic generator in secure digital chaotic communication system.
