Abstract :
Turbo code is proposed for underwater acoustic communication (UWA) based on orthogonal frequency division multiplexing (OFDM). In this paper, performance of turbo code under different modulations are studied and simulated. Simulation results proof that turbo code has a better performances than other method which not use channel code or use convolutional code in higher signal-to-noise (SNR), when using different modulation but has the same frequency bandwidth efficiency.
