A Study on Scattering from Objects in Microcell Urban Prpagation Channel

We analyze the urban propagation channel through careful investigation of the data obtained from a series of wideband measurements. We try to estimate the wave scatterers in the channel by comparison of the cluster received waves appearing in the directional power delay profiles (PDP) to precise maps of the environments including all present objects. The analysis of the measurement results shows that a significant amount of received power has been scattered by identified objects. These objects are signboards, street lights, traffic signs, traffic lights, electricity cable boxes, vending machines and generally any metallic object in the vicinity of any of Tx or Rx up to 100 meters. The contribution of the identified objects scattering to the non-LoS part of the received signal can be up to 40%.
