Abstract

In this paper, an analysis of MIMO system for the transfer of image based on the transmit diversity; employing Alamouti Space-time block coding over Rayleigh Fading Channel is determined. The zero-forcing equalizer is employed for the purpose of equalization. It comprises of STBC and Alamouti STBC theory with its mathematical expressions. The results for image transmission using 2×1 and 2×2 Alamouti STBC are evaluated for different SNR values. The alterations in the value of antennas are carried out between 1 and 2. The transmitted image is modulated using M-PSK modulation technique, and its reconstructed version is plotted as an output function.  The inverse relationship between the SNR values and BER values is shown in the results which depicts that the high value of SNR or number of receiver antennas leads to enhance the system efficiency with the decrease in BER value, and it results in the distortionless recovered image, but an addition to the M value of M-PSK modulation do increase the BER.
