Spatial-Temporal Channel Model and Smart Antenna System Performance Simulation

Performance simulation is very important to the research of smart antenna technology, which is one of the key technologies in third generation mobile communications. This paper introduces smart antenna system simulation methods based on Matlab/Simulink platform. First, a spatial-temporal channel model for the simulation is established together with its realization method in simulation. Then, spatial-temporal signal processing architectures and smart antenna algorithms are discussed and a general simulation flow chart is provided. Finally, several useful methods for smart antenna performance evaluation are described with examples in the research on new smart antenna techniques.
