An Accelerated Frequency Domain Ray-tracing Simulator for Ultra-Wideband Communications
نویسندگان
چکیده
Ray-tracing is an established technique for modelling wireless propagation over a large area in an efficient manner. Existing frequency domain ray tracing simulators incur severe computational burden when extended to model an Ultra-Wideband (UWB) channel of several Giga-Hertz. We propose an acceleration algorithm that improves the efficiency of such simulators by approximating the frequency domain response of individual ray at a reduced set of frequency points. Result show time savings up to 75% with a maximum relative error in the region of 0.8%.

Channel characteristics of ultra-wideband systems with single co-channel interference
In this paper, the channel characteristics of ultra-wideband systems with single co-channel interference are investigated. A ray-tracing technique is developed to calculate channel frequency responses in an indoor environment, of which the frequency dependence for the dielectric constant and the conductivity are carefully considered. By using the frequency responses, the channel capacities with...
متن کاملDesign of the Compact Ultra-Wideband (UWB) Antenna Bandwidth Optimization Using Particle Swarm Optimization Algorithm
In this paper a particle swarm optimization (PSO) algorithm is presented to design a compact stepped triangle shape antenna in order to obtain the proper UWB bandwidth as defined by FCC. By changing the various cavity dimensions of the antenna, data to develop PSO program in MATLAB is achieved. The results obtained from the PSO algorithm are applied to the antenna design to fine-tune the bandwi...
متن کاملUltra-Wideband Indoor Channel Modelling Using Ray-Tracing Software for through-the-Wall Imaging Radar
This paper presents a new software for design of through-the-wall imaging radars. The first part describes the evolution of a ray tracing simulator, originally designed for propagation of narrowband signals, and then for ultra-wideband signals. This simulator allows to obtain temporal channel response to a wide-band emitter (3 GHz to 10 GHz). An experimental method is also described to identify...

The U-slot micro-strip patch antennas were originally developed for bandwidth broadening applications. This study presents a transmission line feed to modify the U-slot stacked rectangular micro-strip patch antenna for Ultra-Wide Band (UWB) communications. The modified antenna has a U-cut loaded with parallel slits and corner slots and is printed on a dielectric substrate of FR4 with relative p...
متن کاملInvestigation of Ultra-Wideband Propagation Channel based on a Cluster Scheme
In this paper, an Ultra-Wideband (UWB) doubledirectional channel sounding measurement and spatio-temporal analysis of UWB propagation based on the clusterization approach were reported. After separating the propagation paths and diffuse components both on the transmitter (Tx) antenna and receiver (Rx) antenna positions, the propagation paths both on Tx and Rx positions were observed for cluster...
