Simulation of OFDM System Modeling and Implementation

This section provides detailed insights into how the simulation accomplishes OFDM system modeling and implements the complete OFDM transmission workflow. The implementation typically involves MATLAB code modules for key operations such as QAM modulation, IFFT/FFT processing, cyclic prefix insertion/removal, and channel modeling. Furthermore, we conduct in-depth analysis of OFDM signal characteristics including time-domain waveform visualization and power spectral density calculations using periodogram or Welch's method. The simulation also incorporates advanced cyclostationary analysis through spectral correlation function computations, examining specific cyclic frequency slices to reveal hidden periodicities in OFDM signals. Additional implementation details cover BER performance evaluation under various channel conditions using Monte Carlo simulations. By enriching these technical descriptions with specific algorithm explanations and function implementations, we can better demonstrate the simulation methodology and results, providing comprehensive understanding of OFDM technology applications.
