Abstract
This paper considers the problems of efficiency estimation of using different types of modulation of hydroacoustic signals of AUV communication, navigation and control systems. The types of signal were investigated: simple signal, linear frequency modulation signal and direct sequence spread spectrum. The signals were compared by the noise immunity, time resolution and detection probability with usage of numerical experiments of correlation signal receiving. Three noise models were performed for computer simulation: additive white Gaussian noise, bandwidth limited noise and real noise realizations. During the simulation a difference in the detection accuracy between the types of signals was found. The correlation receiver showed the greatest error under the real channel noise.
