Underwater acoustic communication systems deal with the problem of fading multipath propagation as well as Doppler shifts. Knowledge of the channel impulse response considerably simplifies the extraction of information from a transmitted signal. Supposed that the impulse response is known at one time instant, the bit-error rate is here studied using that impulse response for the equalisation at later instants, to get a picture of the time variability of the channel. The study is performed by computer simulations with different modulation schemes using channel impulse responses determined from measurements in the Mediterranean during Yellow Shark 94.
