Utilization of channel emulation to accurately characterize the effects of multi-channel RF interactions on MIMO-based systems

The foundation of the next generation of 4G wireless broadband technologies, including WiMAX, LTE and UMB, is multiple-input multiple-output (MIMO) technology. Channel emulation can be used to accurately characterize the effect of RF interactions on the conformance, performance and interoperability of MIMO-based 4G technologies, providing a broad and cost-effective solution to predict performance in a real-world environment and test whether MIMO algorithms are working properly.
