Abstract
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 of the transducer under study, while they differ by the different
modulations they present. In this sense, we study modulations with sweeps (4 to 40 kHz), in which
represent binary codes (zeros and ones), getting closer to the application in acoustic
telecommunications. The different properties of the transmitting signals in terms of communication
speed, directivity, efficiency and power needed are discussed as well.
