Emulation of 3GPP SCME power‐delay profiles for characterisation of multiple‐input–multiple‐output antenna in reverberation chamber

Abstract

A simple yet effective technique for emulating third generation partnership project spatial channel model extended (3GPP SCME) power‐delay profiles in a reverberation chamber is investigated. Through use of a conventional vector signal generator and oscilloscope, urban macro‐ and micro‐environments containing several strong reflections are replicated with <4% error. The generation of the input power delay profiles, the measurement set‐ups in the reverberation chamber and the emulation optimisation process are described rigorously. In experiment, it is demonstrated that the averaging procedure is essential for acquisition of optimum results in the reverberation chamber. The radiation efficiency and correlation coefficient of a multiple‐input–multiple‐output (MIMO) antenna are also defined for different emulated multipath channels. The calculated results verify the efficacy of the proposed emulation method for MIMO antenna characterisation.
