Abstract: The main objective of the MIMO-OFDM system is to add OMDM technology with the techniques of OMDO technology. Increasing demand for multimedia services and the development of Internet-related content increases interest in high-speed communication. OFDM is a type of multichannel modulation that divides the same channel into several parallel sub-channels or suborders so that many symbols can be sent in parallel. OFDM system spreads the information over number of transporters which are at particular predefined frequencies. This diminishes or eliminates the ISI. Forward blunder amendment or channel coding is a strategy utilized for controlling mistakes in information transmission over inconsistent or boisterous correspondence channels. The goal of our proposed paper is to execute the FEC into the MIMO OFDM frameworks and its execution is dissected by utilizing MATLAB over various blurring channels. For adjustment it utilizes M-QAM which consolidates both ASK and PSK along these lines empowering a few bits to be transmitted per image.
