Small Scale Characterization of Underwater Acoustic Channels

UnderWater Acoustic (UWA) channel models provide a tool for predicting the performance of communication systems prior to system deployment and are thus essential for system design. Small-scale modeling of the UWA channel targets statistical characterization of random effects such as scattering and motion-induced Doppler shifting. In this paper, each transmission path is modeled as consisting of micro-multipath components that cumulatively result in a complex Gaussian multiplicative distortion, whose time- and frequency-correlation are assessed analytically. Motion of the surface and transmitter/receiver displacements introduce additional variation whose temporal correlation is modeled via Bessel-type functions.
