Interference Simulation for Direct Sequence Spread Spectrum Transmitters and Receivers with Smart Jamming

This simulation program for smart jamming interference on Direct Sequence Spread Spectrum (DSSS) transmitters and receivers serves as a comprehensive tool for modeling and studying interference phenomena in communication systems. The program comprises multiple functional modules including communication transmitter circuitry, receiver acquisition circuits implementing sliding correlation algorithms, code tracking loops utilizing early-late gate detectors, carrier acquisition circuits with phase-locked loop (PLL) implementations, false lock prevention mechanisms through threshold comparison algorithms, signal-to-noise ratio estimation modules using statistical analysis methods, and data demodulation circuits employing correlation detection techniques. Through detailed simulation and analysis of these circuit components, researchers can gain deeper insights into how interference impacts communication system performance and develop effective countermeasures. The simulation employs MATLAB/Simulink-based modeling with configurable parameters for spreading codes, jamming-to-signal ratios, and channel conditions. This interference simulation program is therefore crucial for researching and enhancing the robustness and performance of modern communication systems against sophisticated jamming attacks.
