Simulation of Chaotic Single-User CSK Modulation

In this research, we implemented a chaotic single-user CSK modulation simulation program to evaluate the bit error rate performance of chaotic modulation. The simulation algorithm involves generating chaotic sequences using logistic maps or similar nonlinear systems, which are then mapped to constellation points for CSK modulation. During the simulation process, we investigated various aspects of data transmission, including channel noise modeling using additive white Gaussian noise (AWGN), multipath fading with Rayleigh distribution models, and signal distortion effects. The core evaluation function calculates BER by comparing transmitted and received symbols under different signal-to-noise ratio conditions. Furthermore, we analyzed different modulation techniques and compared their performance across various channel conditions through Monte Carlo simulations. These observations and analyses yielded conclusions that provide guidance for future chaotic modulation research, while also offering practical insights for real-world applications.
