Both techniques are applied to power delay profiles (PDPs) measured in a indoor environment at 1.95 GHz on a 160 MHz channel bandwidth and the matched filter technique is used for the sounding. The RMS (root mean square) delay spreads are determined from these filtered PDPs and from the original ones. So, for all positions of the receiver, they are compared and the quadratic mean error is evaluated.

Measurements were performed at 1.95 GHz with a 160 MHz channel bandwidth. Time domain sounding technique using PN-sequence with a matched filter was employed. Empirical and theoretical prediction using the Saleh -Valenzuela model and the Finite-Difference Time-Domain (FDTD) method, accelerated via GPU technology, were respectively carried out. So, a comparison between theoretical and experimental simulation is presented.
