Accuracy analysis of GO/UTD radio channel modelling in indoor scenarios including cross-polarisation

The accuracy of a ray-tracing technique based on a full 3D implementation of GO/UTD is investigated by comparison between measurements and simulations carried out at several indoor wireless environments and at two different frequency bands: 1.8 and 2.4 GHz. The narrow-band analysis shows that both the mean level of the received signal and the statistical behaviour of its variations about the mean can be accurately estimated The capability of simulating cross-polarisation is also analysed, showing comparisons of measured versus simulated data. In the wide-band analysis, the comparison between measured and predicted power delay profiles shows that both the amplitude and the arrival time of the main multipath components can be well predicted. The statistical distributions of the measured and simulated wide-band parameters are also compared.
