Abstract: MIMO-OFDM (multiple input and multiple output Orthogonal Frequency Division Multiplexing) system is a new wireless broadband technology which became famous for being capable of high data rate transmission & robustness against multi-path fading. Fading effects must be mitigated at the receiver before demodulation by using equalizer techniques. Equalizer is used to allow recovery of the transmit symbols, which is the major factor responsible for the BER. OFDM has many numbers of sub-carriers.
