Measurement, Modeling and Performance of the MIMO Channel

Abstract

Environmental properties, array geometries and antenna patterns impact the modeling and performance of the multiple-input-multiple-output (MIMO) wireless channel. This paper investigates the phenomenon, model-ing, and impact on the Shannon capacity of angular clustering of multipath and of the line-of-sight (LOS) component of a short-range MIMO link. Clus-tering of multipath angles of arrival has been observed in both indoor and outdoor environments and reduces the capacity of the MIMO link. The LOS component of a short-range MIMO link is shown to have non-unity rank and to dominate the capacity of measured channels. To fully exploit this MIMO channel feature, antennas must be spaced sufficiently far apart. The final topic of the paper is the use of antenna selection and beam selection to provide an SNR advantage to a MIMO link, in conditions either with or without inter-ference.
