In recent years, the need for high speed data transmission is increased. OFDM is a promising solution for achieving high data rates in mobile environment, due to its resistance to ISI, which is a common problem found in high speed data communication. A multiple input multiple output(MIMO) communication system combine with the orthogonal frequency division multiplexing (OFDM) modulation technique can achieve reliable high data rate transmission over broadband wireless channels. MIMO-OFDM combination is widely used in 4G technologies such as WI-MAX and LTE. Cyclic Prefix is very important aspect in OFDM systems. Interference can be reduced by increasing Cyclic Prefix length. But it can have adverse effect on Bit Error Rate performance. Research can be done on determining optimum length of Cyclic Prefix which can provide optimum solution in terms of BER and interference.
