Simulation and Performance Analysis of Time Domain Equalization in OFDM Systems

In this study, we focus on the simulation and performance analysis of time domain equalization in OFDM systems. Initially, we perform simulation analysis on a basic OFDM system implementation to evaluate its fundamental performance characteristics. This includes implementing core components such as serial-to-parallel conversion, IFFT modulation, cyclic prefix insertion, and corresponding demodulation processes. Subsequently, we extend our analysis to evaluate OFDM system performance under multipath channel conditions, incorporating channel modeling and equalization techniques to assess behavior in complex communication environments. Finally, we conduct simulation analysis of the MMSE (Minimum Mean Square Error) algorithm to investigate its effectiveness in time domain equalization. Through these comprehensive simulations and performance evaluations, we gain deeper insights into OFDM system capabilities and the applicability of various equalization algorithms in different operational scenarios.
