Detailed Documentation

This documentation provides a complete OFDM system modeling implementation in MATLAB. The system includes main program modules for OFDM modulation and demodulation, supporting various digital modulation schemes: BPSK, QPSK, 16QAM, and 64QAM. The implementation handles key OFDM processing stages including cyclic prefix addition to mitigate inter-symbol interference, windowing techniques for spectral shaping, and spectrum visualization. The code also incorporates Peak-to-Average Power Ratio (PAPR) calculation algorithms to analyze signal power characteristics. Furthermore, the system includes comprehensive Bit Error Rate (BER) statistical functionality, enabling performance evaluation under different channel conditions. The MATLAB implementation uses matrix operations for efficient symbol mapping, IFFT/FFT transformations for multicarrier modulation, and includes configurable parameters for flexible system testing and analysis.
