Measurements and Wideband Channel Characterization for Over-the-sea Propagation

Abstract

This study focuses on sea propagation environments and presents results on the characterization of the over-the-sea wideband mobile radio channel. Conducted measurements led to the development of path loss, log-distance models. The behavior of the power delay profile is also investigated in detail. In general, the mean excess delay and delay spread values were estimated below 0.5 musec for line-of-sight propagation. However, loss of line-of-sight can cause rapid worsening of the propagation parameters
