Summary:
New wireless standard protocols such as HSPA, LTE, and WiMax are employing multiantennas on both the terminal and base stations sides. This technology, called Multi-input Multioutput (MIMO) enhance system performance especially in a strong multipath and fading environment. MIMO system performances are strongly dependent on antenna properties and the channel environment. MIMO and multi-antenna terminals cannot be reliably tested with the current Single Input Single Output (SISO) OTA (Over The Air) methodology [1], [2]. In multi-antenna communication systems, radio channel characteristics play an important role and SISO typical figure of merit do not take into account radio channel characteristics, and hence are not suitable for testing performances of multi-antenna terminals. 3GPP and COST2100 are looking for a standardized way for radiated performance testing [3], [4], [5], The Spatial Fading Emulation (SFE) technique relies on an anechoic chamber, antenna array, channel emulator, where a realistic multipath propagation environments can be emulated in an anechoic chamber with a number of transmitting antennas surrounding the device under test (DUT), all transmitting simultaneously, and fed by a channel emulator. In this paper, overview of the SFE technique for testing multi-antenna terminals in a multipath and fading environment is presented. Practical consideration as well as results of a testing campaign will also be presented.
