Chaos-based communication offers enhanced security and resilience against interception. However, practical implementation is often hindered by hardware constraints and complex signal processing. This paper presents a Frequency-Modulated Antipodal Chaos Shift Keying (FM-ACSK) system that leverages digital hardware to overcome analog system limitations. Implemented on an Intel Cyclone V FPGA and modeled using Matlab Simulink, this design enhances security while ensuring efficient modulation. Frequency modulation enhances robustness against carrier frequency offsets and ensures a constant signal envelope. The system’s white noise performance in a time-invariant selective fading channel is analyzed through bit error rate (BER) testing, confirming its feasibility for secure digital communication and multipath interference resistance.
