Compact Radio Channel Emulator for MIMO Verification

摘要

A transition is underway in the wireless communications industry as wireless cellular devices migrate from 3G to 4G technologies such as LTE. For 4G products it is necessary to upgrade existing SISO test systems to MIMO capable test systems. This does not just mean multiplying the test hardware, but updating the test system capability to address the MIMO radio channel characteristics such as spatial correlations, power polarizations and antenna radiation patterns, too.
