Low frequency mobile communications in underwater networks
We present a receiver for low frequency underwater acoustic communications addressing the Doppler shift that occurs during the transmission of frames at a very low data rate. The receiver handles constant or variable (linearly and nonlinearly) Doppler shift patterns. The waveform supported by the re...
