OFDM Bit Error Rate Performance Simulation

This complete OFDM simulation program, developed using MATLAB simulation software, enables comprehensive simulation and analysis of OFDM bit error rate performance. The implementation includes key MATLAB functions for generating OFDM signals, applying various modulation schemes (QPSK, 16-QAM, etc.), and adding cyclic prefix to mitigate inter-symbol interference. The program allows simulation of diverse OFDM system parameters and channel conditions, facilitating system performance evaluation and design optimization. Through MATLAB's communication toolbox functions, the simulation incorporates channel modeling for AWGN, multipath fading, and different interference scenarios. The code structure includes modules for transmitter chain (symbol mapping, IFFT operation), channel impairment modeling, and receiver chain (FFT, demodulation, BER calculation). This simulation tool supports research and verification of various OFDM modulation/demodulation algorithms, along with performance analysis under different interference conditions and channel fading scenarios. The program utilizes MATLAB's error rate calculation functions to generate BER vs. SNR curves, providing quantitative performance metrics. Overall, this simulation program serves as a valuable tool for researchers and engineers to better understand and improve OFDM systems through practical code implementation and parameter testing.
