Carrier frequency (Hz).
Power spectral denisty of ambient noise (dB re uPa^2/Hz).
Water salinity (ppt).
Spreading loss factor (between 1 and 2, 1 = cylinderical, 2 = spherical).
Water temperature (deg C).
Nominal water depth (m).
Creates the acoustic channel model.
Computes total noise power in communication band.
Computes received signal power (Urick 3rd ed, p111). Takes into account spreading loss and frequency-dependent absorption (Urick 3rd ed, p105).
rx
- details of the received frameComputes sound speed in water (Mackenzie, JASA, 1981).
