A Jointly Optimized Variable M-QAM and Power Allocation Scheme for Image Transmission

A Jointly Optimized Variable M-QAM and Power Allocation Scheme for Image Transmission

We introduce an improved image transmission scheme over wireless channels with flat Rayleigh fading. The proposed scheme jointly optimizes bit power and modulation level to maximize the peak signal-to-noise ratio (PSNR) of the reconstructed image and hence improves the perceptual quality of the rece...
