【简　介】:Orthogonal frequency division multiplexing (OFDM) is a
popular method for high data rate wireless transmission. OFDM
may be combined with antenna arrays at the transmitter and
receiver to increase the diversity gain and/or to enhance the
system capacity on time-variant and frequency-selective channels,
resulting in a multiple-input multiple-output (MIMO) configuration.
This paper explores various physical layer research
challenges in MIMO-OFDM system design, including physical
channel measurements and modeling, analog beam forming techniques
using adaptive antenna arrays, space–time techniques for
MIMO-OFDM, error control coding techniques, OFDM preamble
and packet design, and signal processing algorithms used for performing
time and frequency synchronization, channel estimation,
and channel tracking in MIMO-OFDM systems. Finally, the paper
considers a software radio implementation of MIMO-OFDM.
Keywords—Adaptive antennas, broadband wireless, multiple-
input multiple-output (MIMO), orthogonal frequency division
multiplexing (OFDM), software radio, space–time coding, synchronization.
