【简 介】:Absrmcr-In this paper, U new orthogonal frequency-division
multiplexing (OFDM) technique for multiple-input multiple
output (MIMO) channels is proposed to reduce interchannel
interference (ICI) caused by high-speed mobiles in cellular
environments. After a closed-form of bit ermr nte (BER) is
derived for MIMO-OFDM systems, the IC1 caused by highspeed
mobile channels is analyzed using a simple m e fining
technique. Then, a new MIMO-OFDM technique, based on the
result of the leakage pattern of IC1 in the frequency-domain,
is proposed for reducing IC1 caused by time-varying channels.
Performances of the proposed technique is veri6ed by using the I.
METRA channel, proposed for an MIMO channel to SGPP, and
an MIMO-OFDM simulator designed for maaocelluar mobile
communication. It is shown by computer simulation that the
pmposed MIMO-OFDM technique is effective in reducing IC1
and noise as well as in obtaining diversitv eain even under hiehlv- ~ ._ ~~ correlated fast fading channels, compaml with the conventional
MIMO-OFDM schemes.
