Detailed Documentation

This source code implements a complete simulation of OFDM communication system performance. The program models various modulation techniques including BPSK, QPSK, MSK, and QAM, and simulates both AWGN (Additive White Gaussian Noise) and Rayleigh fading channels. The implementation follows a modular approach with separate functions for modulation/demodulation, channel modeling, and OFDM frame processing. Specifically, the code includes a detailed simulation of IEEE802.11a-compliant OFDM systems featuring pilot insertion techniques to improve system reliability. Key algorithmic components include constellation mapping, inverse Fast Fourier Transform (IFFT) for transmission, FFT for reception, and channel estimation methods using pilot symbols for equalization.
