LUO Fei, DU Ming-hui. An Enhanced Elliptical Scattering Model for Space-Time Wireless Channels[J]. Acta Electronica Sinica, 2006, 34(12): 2200-2203.DOI:
Spatial-temporal modeling of radio channels is the key for space-time wireless channel study.The widely used geometrically based single bounce elliptical model(GBSBEM)has the limitations in the description of Time-Of-Arrival(TOA).By introducing two physical concepts of effective scatterer and reflecting probability to GBSBEM
an enhanced elliptical scattering model is presented
while the probability density functions of TOA and Angle-Of-Arrival(AOA)are also derived.The detailed analysis proves that the enhanced model not only overcomes the limitations of GBSBEM
but also has an advantage of broad application extent.
