Detailed Documentation

This paper investigates methods and research outcomes for OFDM communication systems to combat multipath fading interference. During this investigation, we particularly emphasize the estimation and compensation of frequency offsets in OFDM systems, which can be implemented using cyclic prefix-based correlation algorithms or pilot-assisted estimation techniques. We conduct in-depth research on this issue from both theoretical and practical perspectives, analyzing existing research achievements while proposing our own solutions involving constellation diagram rotation compensation and phase-locked loop (PLL) implementations. Through this study, we aim to make significant contributions to the stability and reliability of OFDM communication systems by developing robust frequency synchronization algorithms that compensate for carrier frequency offsets through digital signal processing techniques.
