Image Transmission Analysis Using MIMO-OFDM Systems

Abstract

This chapter demonstrates various ways for transmitting an image file using MIMO-OFDM systems which have anti-error ability to reduce BER. Furthermore, various diversity combining techniques like maximal ratio combining (MRC), selection combining (SC) are incorporated along with transmitting diversity scheme (i.e., beamforming). Different modulation techniques (viz. QPSK, 16-PSK, and 64-PSK) are used and evaluated in terms of BER vs. SNR considering different combination of transmitters and receivers. Lastly, results showed that in the transmission course, BER is considerably reduced and the image quality is found much better in comparison to other schemes.
