Abstract: In this research, we present a comprehensive study on the performance of chaotic communication systems under Gaussian and color noise. We selected the most useful systems for short range communications: Chaos Shift Key (CSK) and Differential Chaos Shift Key (DCSK) systems. Logistic map and tent map have been used to generate Chaos in these systems. Color noise has been generated by filtering Gaussian noise via. an FIR digital filter. Various spreading factors have been used. Although, DCSK outperforms CSK in complexity, it is shown that CSK outperforms DCSK under Gaussian and color noise and various spreading Factors (SF) in terms of Bit Error Rate (BER). In addition, it is shown that CSK is more secure than DCSK. both systems have been simulated using MATLAB R2018a.
