Dynamic control techniques such as rank adaptation are studied for LTE (Long Term Evolution) and IMT-Advanced which are promising candidate for next generation mobile communication systems. In order to evaluate these techniques, we need to model dynamic channel characteristics. Meanwhile, Ray-tracing is effective tool for estimation of propagation channel, there are very few studies about estimation accuracy of that tool for the dynamic channel properties. In this paper, we evaluate the above mentioned estimation accuracy based on the measurement results obtained using channel sounder in the urban area. Specifically, we calculate channel parameters such as Mean Angle (MA), Angle Spread (AS), Mean Delay time (MD) and Delay Spread (DS) from ray-tracing and measurement results and calculate correlation coefficient between channel parameter obtained from Ray-tracing and that obtained from measurements for the metrics for the estimation accuracy. As a results, we clarify that correlations of MA and MD are relatively high, and ray-tracing simulates dynamic properties of dominant paths well. |
