Detailed Documentation
This program plots consecutive OFDM subcarriers in the time domain to demonstrate their sensitivity to Carrier Frequency Offset (CFO). The implementation generates orthogonal subcarriers using inverse fast Fourier transform (IFFT) operations and introduces controlled CFO perturbations to simulate real-world synchronization errors. Additionally, the code allows for systematic phase adjustments of OFDM subcarriers to observe their impact on system performance. By analyzing different CFO values and phase configurations through parameterized simulations, users can gain deeper insights into OFDM system stability and robustness. The program outputs time-domain waveforms and comparative analysis plots, serving as a valuable tool for optimizing OFDM system performance and enhancing transmission efficiency through quantitative sensitivity analysis.
