Channel models are vital for theoretical analysis, performance evaluation, and system deployment of the communication systems between transmitter receivers. For sixth-generation (6G) wireless networks, channel modeling characteristics analysis should combine different technologies disciplines, such as high-mobil-ity, multiple mobilities, uncertainty motion trajectory, non-stationary nature time...

This study tests the assumption that the characteristics of channels within multiple channel rivers are different from those of single channel rivers. Some river restoration approaches propose radical transformation of river patterns, from multiple to single channels, based on the link between river patterns and their in-channel characteristics. Determining the links between river patterns and ...

Background: Characteristics of human tissues have direct effects on transmission property of the current signal in human tissues. It is learned from anatomy that, characteristics of all human tissues are not identical, and some like skin and fat are isotropic, while others like muscle are anisotropic. Muscular tissue has a great effect on transmission and distribution of the current signal in h...

this paper describes a simple, physically-based conceptual model utilizing watershed drainage characteristics for rainfall-runoff simulation. this conceptual physiographic model is essentially based on the work of najafi (2003), which has led to a model compris-ing the main tributary subwatersheds and a single main channel subwatershed. the ki-nematic wave (kw) theory is used to describe flow o...

This paper proposes a stochastic multipath model useful for generating MIMO channel matrices in timevariant environments. The multipath model is developed by first extracting the relevant characteristics from measured indoor channel data and subsequently capturing these characteristics in an auto-regressive stochastic model. This model is then used to generate channel matrices whose space-time ...

The wireless sensor networks used in large-scale orchard must be able to run in various environments including different heights and densities of fruit trees. Moreover, as the radio channels have different propagation characteristics in different environments, it is important to study the propagation characteristics of wireless channel in orchards environments. This paper studied the propagatio...
