Abstract :
High data-transmission rate and reliable communication is a challenge for Underwater Acoustic Channel (UAC). The UAC is frequency-dependent subjected to multipath, and low speed of sound propagation. In the presence of existing noise and interference, for effective communication selection of proper Codec (Coding Decoding) Technique and Modem (modulation and demodulation) are essential. In this paper we have discussed the existing three different codec (algebraic, trellis and iterative) technique and advantage of basic digital modulation (PSK, QPSK, FSK) used in UAC communication.
