Generation of 3-D physical fading channel with non-isotropic scattering

This paper presents the application of autoregressive (AR) methods in 3-D fading channel modeling and generation. It employs the AR method to yield the filter coefficient in the 3D and non-isotropic scattering environment, and derives the channel statistics from the geometry-based stochastic channel model (GSCM). Simulations show that the statistical variable of simulated channel agrees with the referenced model. Moreover, by exploiting the Agilent advanced design systems (ADS) software and the Agilent E4432B vector signal generator, the above AR model can be realized in ADS, and then the physical fading channel can be generated through the E4432B instrument. The tests of frequency analyzer demonstrate that the proposed scheme can generate the physical fading channel precisely by the design requirement.
