Simulation of OFDM System with BPSK Modulation

This simulation program implements an OFDM system using BPSK modulation and orthogonal frequency division multiplexing technology. The code models the complete signal transmission and reception process in wireless communications, enabling comprehensive analysis of system performance and reliability. Through MATLAB-based implementation, users can test various parameters and configurations including modulation schemes, carrier frequencies, and channel bandwidths to optimize system performance. The program structure incorporates BPSK modulation through binary symbol mapping, OFDM modulation via IFFT operations, and channel modeling with additive white Gaussian noise (AWGN). By modifying the code parameters and extending functionality, researchers can explore OFDM applications in digital audio broadcasting (DAB), digital television (DTV), and other communication domains. This simulation serves as a powerful toolkit for investigating and enhancing wireless communication technologies to meet evolving communication demands, with built-in functions for BER calculation, constellation diagram visualization, and spectral efficiency analysis.
