Abstract

This paper presents a comparison of two power delay profile filtering techniques, the Relevance Vector Machine - RVM - and the Constant False Alarm Rate - CFAR. 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.
