MATLAB Code Implementation for BPSK Simulation

This document provides a detailed explanation of concepts and performance parameters. Specifically, the BPSK simulation program is a computer-based implementation designed to simulate Binary Phase Shift Keying (BPSK) modulation techniques. Through MATLAB coding, the program typically involves generating random binary data, applying BPSK modulation (where binary 0 and 1 are represented by phase shifts of 0 and 180 degrees), adding Additive White Gaussian Noise (AWGN) to simulate various channel conditions, and implementing demodulation with error detection algorithms. The simulation evaluates Bit Error Rate (BER) performance under different signal-to-noise ratio (SNR) conditions, enabling assessment of communication system reliability. Key implementation aspects include: generating pseudo-random sequences using rand() or randi() functions, applying constellation mapping for modulation, computing Euclidean distance for demodulation decisions, and comparing transmitted/received bits for BER calculation using bit error comparison loops. Through this simulation program, we can observe how BPSK modulation performs under varying SNR levels and interference conditions. BER simulation serves as a crucial metric for evaluating system performance by simulating error rates during transmission, helping engineers understand transmission quality and reliability across different operational scenarios. Therefore, utilizing BPSK simulation programs and BER analysis becomes essential during communication system design and performance evaluation phases.
