KCG Lab

At KCG Lab we are making use of the CUDA parallel computing platform in order to compute complex Radio Frequency problems. Computing radio-maps is a challenging task and requires significant CPU resources. In particular modern RF propagation models take into consideration interferences, multi-paths and complex RF-prediction calculation such as multi-level ray tracing.

Example for multi-path ray-tracing within a complex building

In this research we are using Nvidia's GPGPU platform (CUDA) in order to compute state-of-the-art RF propagation over complex terrains. This eliminates the need to use large scale cluster of computers (or super computers) for this task. This project consists of several RF-propagation models including:

• Urban WiFi: In-Door 3D Ra-tracing for 2.4GHz WiFi channel and signal strength predication. This work is being done as a part of the Israeli Short Range Consortium (ISRC).
• Urban and Suburban WiMax: A 2.5D Ray-tracing and beam tracing for low frequency WiMax & LTE propagation models and parallel Radio-map calculation implementation
• GPS & Galileo Channel Simulator: implementing a multi-path simulator for global position satellite communication in urban resounding (both on L1 & L2 frequencies & modulations)
