Abstract—In this document a numerical validation of the decomposition method is presented. This is a powerful method to split MIMO (multiple input multiple output) enabled UE (user equipment) tests in a radiated and a conducted part to save measurement time.
The concept and fundamental properties of this procedure are introduced. The aim is to show the validity under certain circumstances of this concept by simulation.
The chosen path is to employ a 2×2 MIMO transmission system. Stochastic and deterministic channel models are used, as Rayleigh channels with no line of sight components (NLOS) and identity matrices. Receiving antenna setups with different characteristics were investigated.
Also the practical behaviour of the method using CTIA (The Wireless Association) LTE (Long Term Evolution) reference antennas has been examined. Therefore the distributions of the antenna condition number and of the deviation between the results are provided.
