MATLAB Code Implementation for BPSK Simulation

In this experiment, we implement a communication simulation using the Binary Phase Shift Keying (BPSK) modulation scheme. By inputting specific parameter values into the simulation program, we can model the complete communication chain and generate bit error rate results. The BPSK simulation involves modulating binary data by shifting the phase of the carrier signal between 0° and 180°, transmitting through an AWGN (Additive White Gaussian Noise) channel, and employing coherent detection with correlator receivers or matched filters for demodulation. Key MATLAB functions used in this implementation include randi() for generating random binary sequences, pskmod() for BPSK modulation, awgn() for channel noise simulation, and pskdemod() for signal demodulation. The program calculates BER by comparing transmitted and received bits using biterr() function, providing valuable insights into BPSK performance characteristics under different SNR conditions. This simulation framework helps researchers better understand BPSK modulation scheme performance and supports evaluation and optimization of communication system designs through parameter variation and performance analysis.
