چکیده
In this report, we propose a modification of the multi-resolution frequency domain ParFlow (MR-FDPF) method that allows simulating radio propagation channels in a frequency range. The performance of the proposed MR-FDPF implementation has been analyzed based on different realistic propagation scenarios. Key-words: ParFlow, TLM, wave propagation, indoor radio propagation, channel simulation, multi-resolution, frequency domain, OFDM. The work has been funded by the FP7 IPLAN Project.

On Predicting In-building WiFi Coverage with a Fast Discrete Approach
A new approach for predicting coverage of wireless LAN at 2.4GHz is presented. Coverage prediction is one of the core parts of indoor wireless LAN planning tools. The main concern it has to deal with is providing a good trade-off between prediction accuracy and computational load. Usual approaches belong to either empirical or deterministic methods. A new perspective has recently been offered t...
متن کاملIndoor radio propagation modeling for system performance prediction
This thesis aims at proposing all the possible enhancements for the MultiResolution Frequency-Domain ParFlow (MR-FDPF) model. As a deterministic radio propagation model, the MR-FDPF model possesses the property of a high level of accuracy, but it also suffers from some common limitations of deterministic models. For instance, realistic radio channels are not deterministic but a kind of random p...
