Detailed Documentation

In this article, we conduct a detailed simulation of Orthogonal Frequency Division Multiplexing (OFDM) systems, presenting waveform characteristics at each processing stage, constellation diagrams for modulation analysis, and spectral properties. The MATLAB implementation includes key components such as serial-to-parallel conversion, IFFT/FFT operations for orthogonal subcarrier generation, cyclic prefix insertion for mitigating multipath effects, and QAM/PSK modulation schemes. We also explain the fundamental principles of OFDM and its application domains while discussing its advantages and limitations in wireless communication systems. Furthermore, we provide practical case studies and research findings to help readers better understand and apply OFDM technology, with code examples demonstrating parameter configuration, channel modeling, and performance evaluation through BER calculations and spectral efficiency analysis.
