Research on Anti-Interference Techniques for OFDM Systems

Research on anti-interference techniques for OFDM systems represents a critical task in wireless communications. We will employ MATLAB simulation environment to conduct experiments, implementing key functions such as cyclic prefix insertion, channel equalization, and performance metric calculation. The evaluation focuses on OFDM systems utilizing cyclic prefix (CP) equalization techniques, analyzing their performance through bit error rate (BER) and frame error rate (FER) metrics under multipath propagation and fading channel conditions. The simulation code will incorporate Rayleigh fading channel models and multipath delay profile implementations to create realistic testing scenarios. Through these quantitative assessments, we can gain deeper insights into system performance characteristics and establish foundational knowledge for further research. This investigation will contribute to improving OFDM system performance while enhancing reliability and stability in practical applications through optimized algorithm implementations.
