4. K-factors Primary Concerns: Solution: K-factors for model B questioned
November 2003
K-factors
Primary Concerns:
K-factors for model B questioned
Lack of LOS components in hot-spots
Solution:
Provided both LOS and NLOS components for all mandatory usage model environments
Provided linkage between environments and which LOS/NLOS combinations to use
Provided onset of NLOS modes

5. Doppler Spectrum Model
November 2003
Doppler Spectrum Model
Concerns:
Better mathematical model needed
Lack of physical meaning to model
No coupling between velocity and spike freq. offset
Poor modeling of spike bandwidth
Poor modeling of spike magnitude
Colin Lanzl, Aware, Inc.

6. Doppler Spectrum Model
November 2003
Doppler Spectrum Model
Solution:
Revised equation provided
Linkage of vehicle velocity to spike location provided
Spike bandwidth determined
Spike magnitude relative to bell-shape maximum determined
