Abstract
When radio signal propagates over the sea, the reflection of sea surface and the scattering of sea waves result in multipath components of the transmitted signal at the receiver. This paper introduces an analytical approach for developing multipath channel model for maritime wireless communications over sea. The presented modeling approach can establish the channel impulse response consisting of specular multipath and diffuse multipath produced by smooth sea surface and rough sea surface, respectively. Specifically, the diffuse multipath is obtained by accumulating diffuse scattering energy from the glistening surface. The methods for deriving specular multipath and diffuse multipath are given in detail. Finally, the numerical results of multipath channel models under different transmission conditions are obtained and analyzed using the introduced channel modeling approach.
