  Abstract

It is necessary to make a channel planning providing that we apply terrestrial cognitive network technologies to the open spectrum of underwater acoustic frequency bands in order to enhance its spectral efficiency. In this paper, we study the determination of the channel bandwidth required for the channel planning of the underwater acoustic frequency bands. For this purpose, a mathematical relationship between frequency and channel bandwidth is derived by employing the frequency and channel bandwidth specifications of existing commercial underwater acoustic communication systems. Specifically, a linear regression analysis based on the least-squares method is conducted by considering a regression model where frequency is an explanatory variable and channel bandwidth is a dependent variable. As a result, the linearity hypothesis of the regression model, the normality hypothesis, and the homoscedasticity hypothesis of the errors are adopted with a confidence level of 95%, respectively. In addition, the significance hypothesis between two variables is adopted with a confidence level of 95%, and the coefficient of determination is roughly 85.7%. Accordingly, the linear regression results including the regression equation, the confidence interval, and the prediction interval can be applied to predict or set the channel bandwidth, as a part of the channel planning.
