A multipath channel emulation system and method are disclosed. In some aspects, the system and method allow for analog emulation of a multipath MIMO wireless channel. Such multipath channel emulation system is used for testing the ability of wireless communication devices to operate in an airlink channel characterized by multipath. In a particular aspect, an impedance mismatch or discontinuity is provided in an open-ended coaxial cable so as to cause multiple back and forth reflections between an impedance discontinuity and an open coaxial cable stub and, optionally, including a delay element to emulate a multi-cluster multipath environment. A plurality of such stub subsystems may be combined as sub-paths in a multipath channel emulator. |
