In this paper, we obtain the MIMO channel characteristics of the corridor environment with a high density 829 MIMO channels at 2.6 GHz with 20 MHz bandwidth. The RUSK channel sounder is applied in the channel measurement campaign, which can obtain the highresolution measurement results. The channel measurement campaign has been performed in classical office corridor and semiopen corridor scenarios. We focus on the characteristics of delay spread and correlation with different antenna polarization. For different scenarios, the crosspolarization power ratio (XPR) and angle spread are also analyzed.
