Creating a fake image from real image is known as image forgery. As we know that images plays very important role in our daily life. We use images for many purposes like advertisements, news etc. With the increase in powerful digital image editing so

The increasing need for high data-rate transmissions over time- or frequency-selective fading channels has drawn attention to modulation schemes with high spectral efficiency such as QAM. With the aim of increasing the “diversity order” of the signal
