Transmission of Image through MIMO Systems with Asymmetric Transmitting Power

Nowadays, transmitting of data through MIMO (Multi Input–Multi Output) systems is a common way for doing this kind of transmission. Some features of these systems like high data rate and more reliable connection are caused to use those for image transmission. In this paper, we use V-BLAST in MIMO system for transmitting of image with 2 suggestion algorithms. At first algorithm transmission power of data are distributed based on their importance. In second algorithm after transmitting some data, we are labeling channel based on pilot data. Then for remaining data we are allocating power transmission based on channel statue. Eventually, asymmetric transmitting power causes to increase PSNR (Peak Signal to Noise Ratio) of received image and decreases power transmission.
