R&S®AMU-K74 MIMO fading
Two baseband generators and four fading channels in one box for 2x2 MIMO tests.
Multiple input, multiple output (MIMO) is used in mobile radio (3GPP release 7, EUTRA/LTE) but also in wireless local (IEEE 802.11n) and regional radio networks (IEEE 802.16, e.g. WiMAX™). The higher the statistical independence of channel characteristics, the better the data rate and transmission quality. For MIMO tests, therefore, simulating these channel characteristics is absolutely essential. Since there is one transmission from each transmitting to each receiving antenna, N2 fading channels have to be provided in the simulator for an N×N MIMO system. Due to the geometric antenna arrangement, the channel characteristics are not independent of each other under real operating conditions. As a result, the individual channels must be intercorrelated to realistically simulate the entire transmission path.
