Abstract Based on the spatial characteristics of multi-path channel,one multi-probe test
method, which emulates the spatial multiple path channels inside the anechoic
chamber by using multiple probe antennas and the channel emulator, is provided in
this paper. Based on the setup, measurements are performed to study the
performance differences of throughput among three LTE devices with multiple antennas
under single cluster Spatial Channel Model Extended (SCME) urban macro-cell/urban
micro-cell channel model.
