OFDM Underwater Acoustic Communication MATLAB Implementation

In this project, we develop an underwater acoustic communication program based on OFDM modulation and demodulation techniques. The implementation includes an acoustic synchronization header to ensure reliable data transmission. The system is programmed using MATLAB, employing OFDM technology for signal modulation and demodulation processes. Key implementation aspects include: - Design of acoustic synchronization header using correlation-based detection algorithms - OFDM modulation with IFFT implementation for subcarrier mapping - Cyclic prefix insertion for multipath mitigation in underwater channels - Pilot symbol insertion for channel estimation and equalization - Demodulation using FFT operations with synchronization error correction The acoustic synchronization header enables improved signal synchronization and correction during transmission. Through this MATLAB implementation, we aim to enhance the reliability and performance of underwater acoustic communication systems by addressing challenges specific to acoustic propagation environments. The code structure includes modular functions for signal generation, channel modeling, synchronization, and error rate calculation to facilitate system evaluation and optimization.
