Experimental studies in a hydroacoustic pool of modulated and demodulated signal to assess the effectiveness of using amplitude modulation in hydroacoustic communication system
Incoming article date: 07.03.2025Experimental studies have been conducted in a hydroacoustic pool on the propagation of an amplitude-modulated signal of a complex shape for communication with underwater objects based on a parametric antenna. The parameters of the hydroacoustic pool are given, the modulation and demodulation modes of hydroacoustic signals are developed. The bit error rate is estimated for each measurement, it is proven that the experiment was carried out under strictly controlled parameters, namely, in the absence of currents, noise and reflections (hydroacoustic pool), the receiver is accurately installed and ideal synchronization of the signal is ensured. There were no unwanted phase and frequency deviations of the transmitted signal, as well as time delays between the transmitter and receiver.
