MATLAB Code Implementation for OFDM Channel Simulation

This program implements Orthogonal Frequency Division Multiplexing (OFDM) channel simulation. The core functionality involves calculating channel characteristics followed by Bit Error Rate (BER) computation and result analysis. The simulation framework allows integration of different channel fading models, such as Rayleigh fading or Additive White Gaussian Noise (AWGN), through configurable parameter settings. The implementation supports performance evaluation of various modulation schemes (e.g., QPSK, 16-QAM) and coding techniques by modifying corresponding function modules. Through systematic parameter adjustments and comparative analysis of experimental data, the program generates comprehensive simulation results that provide valuable references for wireless communication system design and optimization. Key algorithmic components include FFT/IFFT operations for OFDM modulation/demodulation, cyclic prefix insertion/removal, and channel equalization techniques implemented through MATLAB's signal processing toolbox functions.
