The underwater acoustic communication scheme of long range deep-water is presented which makes use of the characters of the deep-water acoustic channel putting the communication modems at the depth corresponding to minimal sound velocity value in order to mitigate the transmission loss to improve the range of communication.The fractional Fourier transform (FRFT) is applied to synchronization acquisition and Pattern Time Delay Shift Coding scheme to mitigate the influence caused by Doppler.The results of computer simulations show that FRFT is more adaptive than copy-correlation in the Doppler shift multipath channel that will conduce to communicate with low bit-error-rate.
