Spatial Correlation and Eigenvalue Statistics Investigation of Wideband MIMO Channel Measurements

Abstract

Spatial correlation is one of substantial factors for multiple-input multiple-output (MIMO) wireless communication systems. The spatial correlation must be therefore taken into account in system simulations. This paper results from outdoor wideband MIMO channel measurements performed at 2.53 GHz with a bandwidth of 100 MHz in urban microcell scenario. The measurements were conducted for vehicular speed of 20 km/h. A 16 elements dual polarized patch receive antenna array and a L-shaped transmit antenna array with 11 vertical polarized monopole elements at the mobile station are adopted for investigating 11times32 MIMO channels. As results, spatial correlation and eigenvalue statistics in frequency selective channels for single and dual polarized antennas are studied
