Angle and Time of Arrival Statistics for a Far Circular Scattering Model
نویسنده
چکیده
To exploit the capacity and performance gains associated with the use of antenna arrays, wireless communication systems require proper understanding of the spatial characteristics of the channel. Scattering models provide both Angle of Arrival (AoA) and Time of Arrival (ToA) statistics of the channel. In this paper, we investigate geometrically based single bounce model that assumes that multipath reflection is caused by scatterers located far from the base station (BS) and mobile station (MS). For this model, analytical expressions for the joint ToA/AoA and the marginal AoA probability density functions (pdf’s) are derived. The results presented in this paper are expected to provide better understanding of the effect of far scatterers.

One of the most important conflicts that shaft spillways have to deal with is vortex formation. This phenomenon leads to some unfavorable effects such as vibration in the body of structures, air entrainment and reduced overflow capacity of the spillway. Among all solutions for disrupted vortex formation, an innovative one called circular piano-key spillway, based upon piano key weir principles ...
