Abstrakt

Over-the-air radiated testing is seen as inevitable
for 5G antenna systems. Simple-sectored multi-probe anechoic
chamber (SS-MPAC) setup is a potential testing candidate to
evaluate 5G antenna systems under real-world propagation
conditions. Validation of emulated channel models in the practical
SS-MPAC setup is essential, since it is important to assure the
target channel models are correctly emulated. In this paper, the
objective is to detect the joint-angle-delay power profile of the
reproduced channels in the SS-MPAC setup, where two joint
angle-delay estimation algorithms are discussed, i.e. an existing
algorithm with high computation complexity as the reference
method and a novel low-cost sequential one dimensional algorithm.
Both numerical simulations and experimental verification
measurements in a preliminary SS-MPAC setup are provided to
validate the two discussed algorithms. The proposed sequential
one dimensional search method is demonstrated to be highly
accurate and effective, and therefore recommended for validation
measurements in the SS-MPAC setups. Measurement setup and
procedure for test environment validation of the SS-MPAC setups
are discussed as well.
