Wide-sense stationary and uncorrelated scattering (WSSUS) assumptions are often applied for the statistical description of wireless communication channels. However, in the case of underwater acoustic channels the WSSUS model is of limited value. The

Various blind synchronization methods built on the maximum likelihood (ML) principle have been proposed, where the addressed scenarios include additive white Gaussian noise (AWGN), single-path fading, and multipath fading channels. We consider ML bli

The Underwater Acoustic Communication (UAC) systems work in communication channels characterized by a large variety of multipath propagation conditions that can additionally change over time. Designing a reliable communication system requires knowled

The Wide-Sense Stationary Uncorrelated Scattering (WSSUS) model has long been viewed as a basic channel model to describe the fading dispersive channel. But non-WSSUS models have more universal applicability when the wireless mobile channel with broa

A suitable and often used stochastical model for the description of the fading behaviour of a time variant and frequency-selective channel is the wide sense stationary uncorrelated scattering (WSSUS) model. Usually, the wide sense stationary process

This paper presents an overview of ultrawideband (UWB) propagation channels. It first demonstrates how the frequency selectivity of propagation processes causes fundamental differences between UWB channels and "conventional" (narrowband) channels. Th

The general property of noncommutativity of linear time-varying (LTV) systems has to be considered when a digital transmission system composed of LTV channel and transmit/receive filtering shall be represented in the equivalent discrete-time domain.
