Detailed Documentation

This article presents the design and implementation of an OFDM communication system, covering key components including signal source generation, Reed-Solomon (RS) encoding, digital signal modulation techniques, OFDM modulation system architecture, cyclic prefix insertion and removal mechanisms, serial-to-parallel conversion processes, OFDM demodulation subsystems, channel estimation algorithms, signal demodulation methods, and convolutional decoding operations. The implementation involves MATLAB/Simulink simulations where each subsystem module is individually validated using test vectors and waveform analysis before integrating into the complete communication chain. The system verification includes evaluating bit error rate performance under various channel conditions, testing synchronization robustness, and validating the end-to-end data transmission accuracy through comparative analysis between original and recovered data streams.
