Abstract :
Recent advancements in radio channel measuring and simulation/emulation technologies have enabled the simulation of recorded radio channel data in real time simulators. The paper presents and compares different methods to simplify radio channel measurement data for channel simulation purposes. Different processing methods are compared by utilizing an air interface evaluation platform. The platform consists of SW radio units, a multichannel simulator and graphical user interface. BER results show that too optimistic results are obtained if only simple standardized models are utilized.
