BPSK Performance Simulation System

This paper presents a BPSK performance simulation system developed using MATLAB/Simulink, which models an Additive White Gaussian Noise (AWGN) channel environment. The simulation system implements key components including BPSK modulator/demodulator blocks, AWGN channel modeling with configurable SNR parameters, and error rate calculation modules. After executing the simulation, users can analyze the performance gain of BPSK-modulated signals under various SNR conditions through BER (Bit Error Rate) versus SNR plots and constellation diagram visualization. This system enables comprehensive evaluation of BPSK modulation performance across different channel conditions, facilitating signal transmission quality analysis and system optimization through parameter tuning and performance metric comparisons. The implementation utilizes Simulink's communication blockset for modulation/demodulation and includes custom MATLAB scripts for data analysis and visualization of results.
