Abstract

For high speed data transmission system quality is a big challenge. In case of multiple-input multiple
output (MIMO) system, orthogonal frequency division multiplexing (OFDM) modulation technique is used to
achieve this target. Inter Symbol Interference has been a great challenge in MIMO system, which is required to be
reduced and it can be achieved by variation in cyclic prefix and modulation technique. Orthogonal Frequency
Division Multiplexing (OFDM) has changing into a awfully fashionable multi-carrier modulation technique for
transmission of signals over wireless channels. OFDM eliminate inter-Symbol-Interference (ISI) and permits the
information measure of subcarriers to overlap while not Inter Carrier Interference (ICI). A MIMO-OFDM
modulation technique an do reliable high rate transmission over broadband wireless channel and Also the result of
the analysis suggest for the better technique in order to improve the BER characteristic of the MIMO-OFDM
system.
