Experimental realization of digital sonar communication (part 2)
Main Article Content
Abstract
This paper presents the results of an experiment on sonar data transfer through the channel by the method of quadrature phase shift keying spread-spectrum. In the experiment it was used the four-way phase modulation. Data were transferred at speeds of 1, 2, 4, 8 kbit/s. According to the experiment it was curves constructed distribution curves of information values of the phase of the acoustic signal, it was made the comparison of the data distribution quantile and quantile of the normal distribution, were provided tests of Yarki-Baer and Lilliyefors, it was made the estimation of the expectation, standard deviation and probability of bit errors.
