Experimentation of Eigenvector Dynamics in a Multiple Input Multiple Output Channel in the 5GHz Band

Much research has been carried out on the production of both physical and non physical Multiple Input Multiple Output channel models with regard to increased channel capacity as well as analysis of eigenvalues through the use of singular value decomposition. Little attention has been paid to the analysis of vector dynamics in terms of how the state of eigenvectors will change as a mobile is moving through a changing physical environment. This is important in terms of being able to track the orthogonal eigenmodes at system level, while also relieving the burden of tracking of the full channel that has to be applied otherwise. In this paper, statistical results from a measurement campaign considering the vector dynamics and the influence of physical parameters are presented and discussed.
