Detailed Documentation
This paper presents an OFDM system simulation using MATLAB Simulink. The implementation utilizes Fast Fourier Transform (FFT) algorithms for both OFDM signal generation and demodulation processes. The simulation incorporates comprehensive channel estimation and equalization functionalities, employing the Least Squares (LS) estimation method for channel characterization and compensation. The LS algorithm is implemented by comparing received pilot signals with known transmitted pilots to estimate channel frequency response. Through this simulation framework, researchers can effectively analyze OFDM system performance characteristics, including bit error rate evaluation under various channel conditions and the impact of different equalization techniques on system robustness.
