Explore MATLAB source code curated for "OFDM" with clean implementations, documentation, and examples.
Implementation of OFDM's autocorrelation cyclic function featuring a 6-path Rayleigh fading channel model with comprehensive delay considerations. The simulation generates cyclic autocorrelation diagrams, cross-sectional plots, and allows customizable Monte Carlo iterations (typically set to 200 runs). Includes MATLAB-based implementation for channel modeling and statistical analysis.
This is an excellent MATLAB simulation program for CP-based maximum likelihood symbol timing synchronization and carrier synchronization in OFDM systems. Developed through in-depth study of classical literature and extensive programming debugging, the code is refined, well-organized, and error-free. The synchronization curves obtained from this simulation perfectly match those in classical references. The implementation features efficient correlation algorithms using cyclic prefix properties and handles frequency offset estimation with maximum likelihood detection. For an OFDM system with N=1024 subcarriers as required by the literature, the program runs in approximately 2-3 minutes.
OFDM (Orthogonal Frequency Division Multiplexing) implements multi-carrier modulation by dividing a broadband channel into multiple parallel narrowband subchannels, where each subchannel experiences flat fading. A complete OFDM channel link system is constructed using three different channel estimation methods (LS channel estimation, DFT channel estimation, and Improved-DFT channel estimation). The system performance is simulated and compared under both AWGN (Additive White Gaussian Noise) ideal channels and fading channels in terms of bit error rate analysis.
