UWB Indoor Radio Propagation Modelling in Presence of Human Body Shadowing Using Ray Tracing Technique

This paper presents a ray-tracing method for modeling Ultra Wide Bandwidth indoor propagation channels. A validation of the ray tracing model with our indoor measurement is also presented. Based on the validated model, the multipath channel parameter like the fading statistics and root mean square delay spread for Ultra Wide bandwidth frequencies are simply extracted. The proposed ray-tracing m...

Radio-wave propagation prediction using ray-tracing techniques on a network of workstations (NOW)

Ray-tracing based radio wave propagation prediction models play an important role in the design of contemporary wireless networks as they may now take into account diverse physical phenomena including reflections, diffractions, and diffuse scattering. However, such models are computationally expensive even for moderately complex geographic environments. In this paper, we propose a computational...

Simulation of Radio Wave Propagation by Beam Tracing

Beam tracing can be used for solving global illumination problems. It is an efficient algorithm, and performs very well when implemented on the GPU. This allows us to apply the algorithm in a novel way to the problem of radio wave propagation. The simulation of radio waves is conceptually analogous to the problem of light transport. However, their wavelengths are of proportions similar to that ...

Parallel radio-wave propagation modeling with image-based ray tracing techniques

Ray tracing is a technique based on the numerical simulation of geometrical optics and the uniform theory of diffraction, two well-known approximate methods for estimating a highfrequency electromagnetic field, based on the ray theory of field propagation. Radio-wave propagation prediction models based on ray tracing play an important role in wireless network planning, as they take into account...

Mobile Radio Propagation Simulation Based on Ray-Tracing Method

あらまし レイトレーシング法は送信点から受信点に到達するレイを幾何学的にトレースするだけで電波伝搬 をシミュレートでき,移動通信のシステム設計やエリア設計に必要な伝搬諸特性を一元的に推定できる魅力的な 方法である.しかし,高精度な結果を得るためには形状と材質(電気的特性)に関する詳細な構造物データを必 要とする.また,広範囲にわたる多くの構造物を対象に相互作用回数(反射,回折,透過)の多いレイをトレー スしなければならず,演算に多くの時間を要する.本論文では,筆者らが開発した市街地マクロセル対応のレイ トレーシングシステムの概要を述べる.本システムには演算処理の高速化を実現するために筆者らが提案してい る様々な高速化技術が適用されている.また,本論文では市街地の実測データと比較することにより本システム の演算時間と推定精度を評価し,本システムが実用に資するものであることを明らかにする...
