“…Moreover, in a recently published highly-cited paper [24], it was shown that nonlinear chirps provide even better performance compared to CSS. There are few papers [25] addressing the employment of continuous-time chaos for spreading, as there is a huge challenge with the implementation of spreading waveform synchronization. If the spreading waveform is purely chaotic, correlation-based techniques can not be employed.…”

This paper is devoted to software-defined radio (SDR) implementation of frequency modulated antipodal chaos shift keying (FM-ACSK) transceiver and presents results of prototype testing in real conditions. This novel and perspective class of spread-spectrum communication systems employs chaotic synchronization for the acquisition and tracking of the analog chaotic spreading code and does not need resource-demanding cross-correlation. The main motivation of the given work is to assess the performance of FM-ACSK in real conditions and demonstrate that chaotic synchronization can be considered an efficient spread-spectrum demodulation method. The work focuses on the real-time implementation aspects of the modulation-demodulation algorithms, forward error correction (FEC) and symbol timing synchronization approach in MATLAB Simulink. The performance of the presented prototype is assessed via extensive testing, which includes measurement of bit error ratio (BER) in single-user and multi-user scenarios, estimation of carrier frequency offset (CFO) impact and image transmission over-the-air between two independent sites and comparison with classical frequency hopping spread spectrum (FHSS). The paper shows that the presented class of the spread spectrum communication systems demonstrates good performance in low signal-to-noise ratio (SNR) conditions and in terms of BER significantly outperforms the classic spread-spectrum modulation schemes which employ correlation-based detection.

“…Several methods have been proposed to transmit digital information using chaotic waveforms, including chaos control [10], synchronization of chaotic oscillators [11], broadband coherent communication [12], symbolic dynamics with reverse iteration [13]. Multiple access schemes have been proposed using chaos shift keying (CSK), differential chaos shift keying (DSCK) [14], correlation delay shift keying (CDSK) [15].…”

In this paper, we propose a methodology to design chaos-based communication systems, which exploits the topological structure of 3-D chaotic attractors. The first step consists in defining a proper partition of a Poincaré section of the attractor and the subsequent encoding of the chaotic trajectories. Then, the evolution mechanism of the chaotic attractor, according to the dynamical restrictions imposed by the chaotic flow, is represented by a state diagram, where each state represents a region of the Poincaré section or a branch in the template of the chaotic attractor. The state transitions are associated with segments of chaotic trajectories that connect the corresponding regions of the Poincaré section. The chaotic signals are transmitted over both additive white Gaussian noise and Rayleigh flat fading channels, and a trellis structure derived from the state diagram is used at the decoder to estimate the transmitted information sequence. Finally, the bit error rate performance of the system is analyzed. INDEX TERMS Chaotic attractors, chaos-based communications, chaos control, error probability, Poincaré section, symbolic dynamics, topology of chaotic systems.
