A radio-coverage prediction model in wireless communication systems based on physical optics and the physical theory of diffraction [Wireless Corner]

High Frequency Techniques: the Physical Optics Approximation and the Modified Equivalent Current Approximation (MECA)

“…Some papers have already proven the validity of the asymptotic approximations at these frequencies. In addition to the previously enumerated fields of application of the MECA method and in spite of the typical employment of Ray Tracing and Launching in joint with empirical models to deal with the radioelectric coverage evaluation (Papkelis et al, 2007), this problem must be added to that list. The reason is that it fulfils all the requisites detailed through this chapter.…”

Tropospheric Propagation above Uneven Ground

“…Several procedures have been described [1]- [11] such as geometrical optics (GO) and various modifications of the geometrical theory of diffraction. Methods like the Finite Element Method (FEM), Frequency Domain Time Difference (FDTD), Method of Moments (MoM) and Integral Methods are rather challenging, considering the memory and Central Processing Unit (CPU) time.…”

A Quasi Three-Dimensional Ray Tracing Method Based on the Virtual Source Tree in Urban Microcellular Environments

“…During the last decade, the progressive deployment of the first extensive public mobile radio networks has spurred researchers toward the study of radio propagation in urban environment and the development of fast and reliable radio coverage prediction models [1,2]. At present, the propagation prediction model can be mainly divided into two categories: one is statistical model, and the other is deterministic model.…”
