Abstract
A new technique for the estimation of coupling
between array elements in MIMO transceivers is presented.
The estimation method is founded on subsequent transmission
and over-the-air (OTA) reception between the array elements,
when the transmitter’s characteristics are unknown. The method
enables accurate on-line characterization of the behavior of
the array in terms of coupling for a complete system with
PAs and antennas connected. The method is validated via OTA
measurements on a four-element array in a MIMO transmitter
configuration. The results demonstrate that the estimated
couplings with the proposed technique are similar to the
ones obtained from S-parameter measurements with deviations
reflecting the operation with antennas and PAs connected. The
proposed intra-array coupling estimation facilitates practical
OTA measurement-based modeling and linearization of MIMO
transmitters.
