This paper addresses the wireless MIMO channel sounding method based on the time domain cross correlation principle. Measurements are conducted in the indoor laboratory environment at the central frequency of 2.3 GHz with a measurement bandwidth of 100 MHz, 4 transmitting and 4 receiving antennas were used. The obtained pulse responses are presented and used for channel parameters estimation. The measured channel capacity CDF curves are also presented. A full channel correlation matrix and its eigenvalues are calculated showing a significant spatial correlation. For statistical analysis the distribution of channel coefficients and goodness of fit tests are numerically computed. The correlated channel capacity is also compared with the uncorrelated channel capacity.
