New space-time wireless channel model and its computer simulation method
Zhai Mingyue, Hua Li · 2005
A channel model is essential for performance analysis in smart antenna systems. Parameters are not easily determined in the GBSBEM (geometrically based single-bounce elliptical model) model, which is commonly used in smart antenna systems. This paper presents a new space-time model, which combines the GBSBEM model and the mobile model suggested by UMTS-IMT-2000. Based on the GBSBEM model, the presented model absorbed some parameters like time delay and power from the UMTS-IMT-2000 suggested model. At the same time, the Doppler effect was also taken into account. The detailed simulation steps are included in this paper. Based on the presented model, a multi-user space-time model was also presented. Computer simulation shows that the presented model is feasible in smart antenna systems.
