Abstract
Underwater communication of autonomous underwater vehicles (AUVs) has intense demands on acoustic modems caused by the continually changing signal propagation due to ambient noise, multipath propagation, and other effects of the underwater acoustic channel. In this extended abstract, we present a model-based approach to generate ambient noise with finite impulse response (FIR)-filters over the desired power spectral density (PSD). Furthermore, we compare commonly used alternatives, like additive white Gaussian noise (AWGN) and Knudsen curve. We show that the ambient noise generated by FIR-filters has the formally desired PSD and provides an up to 15 % better estimation for a selectable frequency spectrum compared to AWGN.

The effect of different subsampling matrices with the same sampling density, on the optimality of two-dimensional filter banks is studied in this paper. It is seen that, in the case of two channel filter banks, there can be three distinct filter banks ...

In this paper, several models are proposed and compared considering multipath attenuation and ambient noise. The models in the time domain and frequency domain all take into account the attenuation calculation along with white and colored noise. In the ...
