Multiple-Input Multiple-Output (MIMO) technology is the foundation of the next generation of mobile broadband wireless products and systems such as those defined by 3GPP for LTE and by other industry groups for other 4G standards. By leveraging multiple transmit and receive antennas to employ techniques such as spatial multiplexing, adaptive antenna processing, and beam forming, MIMO-enabled products deliver greater wireless throughput and range enabling ubiquitous high-speed voice, video and data services. To accurately characterize the effects of multi-channel RF interactions on the conformance, performance and interoperability of MIMO-based systems in a laboratory environment, channel emulation is required.
