Abstract: In wireless systems the orthogonal frequency division multiplexing (OFDM) is one of the most influential means of transmission techniques. Data channel having higher speed are converted into some parallel channels by OFDM. For better performance of wireless network, cooperative communication using multiple relay is widely used. Substantial improvement can be achieved in case of reliability and throughput for wireless network if multiple relays are implemented between the source and destination by developing cooperative communication with multiple input multiple output (MIMO) OFDM. A mathematical model has been developed based on amplify and forward (AF) multiple relay for the system of cooperative MIMO-OFDM. Along with the detection system based on minimum mean squared error, the cooperative MIMO-OFDM, with multiple relays, can provide better performance than transmission system using single relay, which can be found from analyzing simulation. A considerable amount of deterioration was also noticed in the color image with changing the number of relays. Signal salvation is better for multiple relay than single relay.
