dc.description.abstractWideband (5MHz) measurements have been performed at 1900 MHz in a typical urban microcell using a synthetic Uniform Linear Array (ULA) at the base station. The Direction of Arrival (DOA) of the received signal is investigated using an Iterative Maximum Likelihood algorithm (IML). A 3-Ray DOA model is proposed to give the basic DOA angular spread profile with a modest T-R distance. A hypothesis of virtual Multiray DOA model is proposed to model the measurements for LOS case. The parameters sensitivity of constitutive parameter of different material, street width, MS position and base station antenna height of the virtual Multiray DOA model is investigated.
