This project presents a relatively complete simulation design of an OFDM communication system, incorporating modules for coding, modulation, IFFT/FFT operations, up/down conversion, Gaussian channel modeling, PAPR suppression, various synchronization techniques, demodulation, and decoding. The system's reliability has been validated through comprehensive performance simulations evaluating key metrics like BER and throughput.
