An accurate and efficient method based on ray-tracing for the prediction of local flat-fading statistics in picocell radio channels

Numerical modeling of an indoor wireless environment for the performance evaluation of WLAN systems

“…This phenomenon describes the time dispersion of the wireless channel, which may lead to intersymbol interference (due to the symbol spreading) and affect system performance. The degree of dispersion is quantified with the aid of the recorded PDPs , from which the root mean square (rms) delay spread is obtained via (3) and is the PDPs mean excess delay…”

Minimum Cell Size for Information Capacity Increase in Cellular Wireless Network

“…Ray theory is a procedure for providing an accurate site-specific means to obtain useful simulation results [64,65]. This technique also serves as a starting point for statistical modelling [66,67]. Ray-tracing method unlike other computational complex modelling tools, is simple.…”

Investigation of Wave Propagation Using Smart Antenna for Indoor Wireless Communication

“…A number of popular numerical simulation methods have been used extensively to perform indoor wireless studies, such as ray-tracing, geometrical optics (GO), uniform theory of diffraction (UTD) [1]- [8], and hybrid ray-tracing-FDTD techniques for similar purposes [9]. Each modeling technique is limited to particular types of models as each numerical technique has its own strengths, and weaknesses.…”
