Query: Enable Super-resolution Parameter Estimation for Mm-wave Channel
  Sounding   This paper investigates the capability of millimeter-wave (mmWave) channel
sounders with phased arrays to perform super-resolution parameter estimation,
i.e., determine the parameters of multipath components (MPC), such as direction
of arrival and delay, with resolution better than the Fourier resolution of the
setup. We analyze the question both generally, and with respect to a particular
novel multi-beam mmWave channel sounder that is capable of performing
multiple-input-multiple-output (MIMO) measurements in dynamic environments. We
firstly propose a novel two-step calibration procedure that provides
higher-accuracy calibration data that are required for Rimax or SAGE. Secondly,
we investigate the impact of center misalignment and residual phase noise on
the performance of the parameter estimator. Finally we experimentally verify
the calibration results and demonstrate the capability of our sounder to
perform super-resolution parameter estimation.
