Delay and Doppler Variations in Device to Device Communications with Pedestrian Mobility

摘要

This paper exploits the Doppler and delay spreads for pedestrian-to-pedestrian (P2P) communications based on a measurement campaign carried out at 3.8 GHz. Several propagation conditions and different mobility patterns were investigated. In particular, the impact of vehicle passing in the vicinity of a P2P links was considered. It was found that the delay spread does not only depends on the propagation environment but also on the body mutual orientation whereas the presence of a moving vehicle in the vicinity of P2P links can have an impact on the Doppler spread.
