We present the results of multiple-input multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) channel measurements. The measurements were performed in indoor environments using four transmitters and four receivers with 40MHz bandwidth at 5.25 GHz. Our measurements reveal two-dimensional small-scale fading, and correlation between MIMO subchannels. In the line-of-sight (LoS) case, the MIMO-OFDM channel capacity is found to be strongly dependent on the local scattering environment; and much less dependent in the non-LoS (NLoS) case. Also, MIMO channel capacity is found to be largely uncorrelated over 20MHz in NLoS, while a strong correlation is found over 40MHz in some LoS environments. The validity of the conventional Kronecker correlation channel model is tested, along with a recently proposed joint correlation model. The effects of varying antenna element spacing are also investigated, taking into account such effects as mutual coupling, radiation efficiency, and radiation pattern.
