Wireless Polarized-Channel Simulator

A wireless polarized-channel simulator is described that can generate a variety of polarized-channel impulse responses. The simulator is useful in the broad research area of polarization-utilizing wireless communication systems. The simulator relies on a geometrically based statistical model (GBSM) for polarized wide-band channels, and consists of three-dimensional (3-D) concentric scattering cylinders about the mobile station. It can be used to model a polarized wide-band cellular down-link channel. To the best of our knowledge, our polarized-channel simulator is the first such simulation model that can generate the time-variant channel impulse response of polarized wide-band wireless fading channels. The simulator utilizes previously reported geometrical theory and reference models for cross-polarization discrimination (XPD), and shows excellent agreement with the reference models, while considering only a finite number of scatterers both for good accuracy and manageable computational complexity.
