Electromagnetic reverberation chambers can be used for multiple‐input multiple‐output (MIMO) systems testing.Currently, the tests focus on parameters such as correlation, diversity gain, efficiency, etc., by using a vector network analyzer. In contrast with these passive tests, a novel way of MIMO systems characterization is described in this article. It consists on evaluating bit error rate (BER) levels of a MIMO WiMAX‐OFDM system according to the Signal‐to‐Noise Ratio (SNR) by establishing an active link between the transmitter and the receiver. The measurement process is set up in a reverberation chamber, where multipath frequency selective channels are emulated. The obtained results are compared to a reference case with single‐input single‐output (SISO) to evaluate the real improvements made by the studied system. © 2010 Wiley Periodicals, Inc.
