Abstract-- OFDM multi-carrier modulation is expected to be
the enabling technology for 4G wireless systems. One of the
features that make OFDM the primary choice for 4G is its
MIMO compatibility, because MIMO has a very significant
potential of enhancing wireless systems for capacity, data rate,
and coverage aspects. In this paper, the challenges of MIMO-
OFDM measurements are addressed in comparison to SISO, with
a special emphasis on WiMAX systems, which employ MIMO-
OFDM technology. It is proposed to perform the reception and
measurement of MIMO-OFDM signals using a single receiver
branch rather than multiple receivers. A complete guide to
perform impairment estimation for WiMAX MIMO signals with
a single receiver according to the 802.16 standards is also
