The multiple-input and multiple-output, or MIMO, is a method for multiplying the capacity of a radio link using multiple transmission and receiving antennas to exploit multipath propagation. Orthogonal frequency division multiple access modulation technique handled efficiently of multipath channel. This paper proposed efficient approach based on Alamouti STBC for channel estimation. Simulation is carried out using MATLAB software. Signal to noise ratio and Bit error rate is the key parameter to check validation of the proposed methodology. PSK is needed to apply with various simulation conditions. Simulated result shows the significant improvement than existing approach.
