[EN] This paper presents a study of different types of parametric signals with application to
submarine acoustic telecommunications. In all of them, the carrier frequency is 200 kHz, which
corresponds to that resonation ...
One of the main problems in underwater communications is the low data rate available due to the use of low frequencies. Moreover, there are many problems inherent to the medium such as reflections, refraction, energy ...
