“…Maurer [9] was one of the first to apply ray tracing in order to model the V2V communication channel. Schmitz [10] used GPU based ray methods to speed up the simulation of radio wave propagation for static transmitter scenarios. Ray launching on GPUs was also employed in [11] to simulate radio propagation in indoor scenarios.…”

Due to the complexity of Vehicular Ad Hoc Networks, future driving assistance systems need to be validated through virtual test drives in a simulated environment. An accurate modeling of the vehicle-to-vehicle communication channel is crucial to enable a precise evaluation of such networkaware applications. Since existing ray-based methods cause long computation times, a new parallel GPU-based ray-launching simulation method is presented. The algorithmic improvements allow a high utilization of the GPU computing power, which results in significantly faster simulations while achieving high accuracy. The validation of the simulation results against realworld measurements showed a high level of agreement.

“…Instead of synthesizing an image, the receivers will plot data over time in the form of spectrograms and histograms. Software packages and other research already exists to perform this type of simulation [9], but most of these works generate coverage maps, whereas with this simulation we need point-to-point signal propagation results only.…”

This paper investigates a method of tracking remote transmitters using a fingerprint localization database generated by raytracing. OpenStreetMap building data is used to model the area of interest, and a database of received signal strength (RSS), time-difference of arrival (TDOA), and angle of arrival (AOA) fingerprints is generated virtually along a grid. These fingerprints are then used to estimate the origin of incoming signals. Simulation of this method using three receivers and a 10m square grid demonstrates a localization accuracy within 15m.

“…Accordingly, antenna and wireless communications engineers have benefited from this powerful tool for wave propagation modeling [2] and used it specifically for the modeling of large electromagnetics problems. Ray tracing channel modeling belong to the deterministic channel modeling methods category which is, unlike the statistical channel modeling [3], accurate but slow.…”

In this paper a generic 2D Ray tracing channel modeling tool is proposed. The proposed tool has been optimized for GPU architecture. Two examples for different types of applications have been presented and used to profile the tool. Comparative results have been presented for different parameters and examples. Due to its high speed, the proposed tool is useful for system optimization for large EM problems such as automotive radar application.
