Summary: IEEE TRANSACTIONS ON INSTRUMENTATION AND MEASUREMENT, VOL. , NO. , 2008 1
MIMO-OFDMA Measurements; Reception, Testing,
and Evaluation of WiMAX-MIMO Signals with a
Single Channel Receiver

Abstract-- The number of MIMO-OFDMA systems is expected
to increase sharply in the near future. Engineers who need to test
these systems face two difficulties. First, the lack of descriptive
instructions to conduct reliable measurements. Second, the in-
creased hardware cost due to the need for multiple transmitters
and receivers. This paper first introduces all measurable pa-
rameters of MIMO-OFDMA systems and provides a clear guide
to perform the measurements specific to various parts of the
system. Then, it proposes to implement reception of MIMO-
OFDMA signals using a single receiver rather than multiple
receivers. For this purpose, impairments related to each of the
RF front-end components are investigated. Challenges of MIMO-
OFDMA measurements are addressed in comparison with SISO.
A complete procedure is provided to receive and do impairment
estimation for WiMAX MIMO signals using a single receiver
