Abstract:

This study investigates the efficiency of different digital communication methods by employing a discrete 2D chaotic signal as the carrier. It focuses on evaluating their noise tolerance in multipath fading channels. The goal is to assess channel performance across diverse fading conditions using various modulation techniques. The analysis examines the BER and SNR characteristics of AWGN, Rayleigh, and Rician fading channels. The findings reveal that Rician channels demonstrably offer significantly superior performance. A comparison table presenting these calculated values is included and discussed. The analysis was implemented using MATLAB code and Simulink.

Keywords:

Chaos-based communication schemes, Digital modulation/demodulation, BER analysis, Fading channel.
