In this letter, we propose closed-form Doppler power spectral densities (DPSDs) for vehicle-to-vehicle (V2V) channels in the presence of roadside scatterers (RSSs). Our analysis is based on a geometrical one-dimensional RSS model, which considers two line segments on both roadsides to represent RSSs. To obtain the exact DPSD, we use an indirect method exploiting Hoeher’s theorem [9]. Then, angular approximations are used to obtain its closed-form solutions. We show that the new solutions are scaled, shifted, and truncated sums of the cubic Jakes’ DPSD and also close to measurement data.
