A Novel Construction Technique for Reduction of Multipath Effects in Indoor Channels (original) (raw)
Abstract - In this report the ultra wide band signals are more affected due to EM waves propagated through irregular shaped bodies such as walls, buildings and hill areas multipath effects, too. MPCs are analyzed for various cases with several antenna heights and distances. Path delays (due to propagation through walls and various paths of direct and reflected rays) and the ringing (similar to UWB propagation through wall) can be clearly observed and analyzed. This paper provides a new proposal where an antenna is used in (40-60GHz) frequency range to reduce the effect of Multipath path fading coefficients. Keywords - UWB, Multipath Fading, EWP

Multipath Propagation of UWB Through-Wall Radar and EMC Phenomena
The UWB (ultra wide band) radar output signals can be substantially affected due to electromagnetic wave propagation through obstacles (such as walls) and multi- path effects, too. Multipath effects are analyzed and simu- lated numerically for various cases with several antenna heights and distances. Delays (due to propagation through walls and various paths of direct and reflected rays) and the ringing (similar to UWB propagation through wall) can be clearly observed and analyzed. Moreover, fre- quency spectra analyses can demonstrate both UWB in- terferences and susceptibility from electromagnetic com- patibility (EMC) viewpoint.
