In this chapter, wideband indoor multi-input and multi-output (MIMO) channel measurement was used to study the performance of the virtual MIMO formed by two users whose channels were measured while standing. In this measurement, 19 datasets are available which result in 19 users. From those datasets, we formed 171 possible virtual MIMO pairs. To set up a virtual MIMO system, two spaced antennas from standard users are taken and brought together. The capacities are evaluated for the standard users and the virtual MIMO system, and the comparison is made between standard users and the virtual MIMO formed by those users. The results show that the use of the virtual MIMO improves capacity in a great proportion compared to standard users. The parameters such as \(K\) -factor, root mean square (rms) delay spread, and spatial correlation, which affect the capacity are also evaluated. The results show that the capacity improvement is mainly due to spatial correlation and rms delay spread reduction rather than the -factor reduction.
