A. Ring of Scatterers Model

In the ROS
model shown in Fig. I, the scatterers are located on a ring centered about the
MS with a radius Rt.. The angular
distribution of the transmitted (or, equivalently, arriving) signal from the MS
is uniformly distributed on 0, 27. In addition, the scatterers are uniformly
distributed around the ring. The true distance between MS and BSi is Ri while
measured propagation distance (i.e., range or TOA measurement) of the jth
multipath component is l zj for a single reflection off the ring.

 

B. Disk of Scatterers Model

In the DOS
model, the scatterers are located an a solid cir- cular disk of fixed radius Rd with
the MS at the center as shown in Fig. 2. The distance to a scatterer from the
MS, rpos, is uniformly distributed in the range 0, Rd, and the angle 0 is
uniformly distributed in the range 0, 27r.

 

C. Clipped Gaussian Scattering Model

Fig. 3
illustrates the geometry for the Gaussian scattering model. While the Gaussian
distribution has tails that extend infinitely (i.e., 0
