A Literature Review on Shallow Water Acoustic Communication using Different Coding Scheme

The underwater acoustic channel (UAC) is known to supply poor communications channel. The channel medium is extremely assimilative and therefore the transmission bandwidth is proscribed. Additionally, the channel is extremely frequency selective; the degree of selectiveness depends on a detailed geometry of the channel. Further, the response changes over time as conditions moving the response (such as water temperature, ocean surface wind, salinity, etc are time-varying. A system design to trot out the frequency and time selective channel in UAC, therefore, becomes terribly difficult. In this review paper review of different technique used in the SWAC in shallow water communication region. The performance parameters of different methods are, first one is the bit error rate (BER) and second one is the frame error rate (FER)
