MATLAB Implementation of BPSK Modulation with Simulink Simulation

This implementation demonstrates Binary Phase Shift Keying (BPSK) modulation using MATLAB, followed by detailed system simulation and performance analysis through Simulink. The approach involves converting digital signals into BPSK modulated signals, where binary data (0s and 1s) are represented by phase shifts of 0 and 180 degrees in the carrier wave. The MATLAB code typically utilizes key functions like pskmod() for modulation implementation and incorporates signal processing algorithms for baseband transformation. The Simulink model provides a visual simulation environment for analyzing system performance metrics such as bit error rate (BER), signal constellation diagrams, and spectral characteristics. This methodology finds applications in various wireless communication systems including wireless sensor networks, mobile communications, and satellite communications. By leveraging MATLAB's signal processing capabilities and Simulink's simulation tools, engineers can efficiently validate modulation schemes, assess system reliability, and verify design accuracy through parameter tuning and real-time performance monitoring. The implementation allows for comparative analysis of different modulation schemes and channel conditions to optimize communication system performance.
