The main difference between WUCNs and the terrestrial wireless communication networks is the communication medium. In this paper, signal propagation characteristics are described in these constrained areas. First, a channel model is described for electromagnetic (EM) waves in soil medium. This model ...
For instance, in wireless communication systems, techniques such asorthogonal frequency-division multiplexing (OFDM) and code-division multiple access (CDMA) rely on sophisticated signal processing algorithms to enable efficient data transmission in the presence of multipath propagation and interference. In ...
The estimates of data rates in the ultrawideband direct chaotic scheme of data transmission in rooms, which can be achieved at a specified level of error probability under the conditions of multipath signal propagation in wireless communications networks, are presented. The estimates have been obtained...
Signal propagation—ionospheric delay and tropospheric delay (caused by atmospheric effects). Following is an alternative classification of errors: 1. Constant errors: These are errors that have nothing to do with the position of the receiver. The errors are already present in the satellite data bef...

direct measures of signal propagation allow us to define mathematical relations that describe how the activity of an upstream neuron drives activity in a downstream neuron, including its temporal response profile. Historically, this and related perturbative approaches have been called many names (Supplemen...
