Orthogonal source adaptive modulation for image transmission over noisy channels

Abstract: This paper presents a low-complexity method of transmitting digitally compressed imagery through AWCN and fading channels. The proposed method combines a wavelet-based image coder that employs phase scrambling and trellis-coded quantization (TCQ), and orthogonal source adaptive modulation (OSAM), which is implemented using time diversity and orthogonal modulation. We compare the performance of the OSAM-TCQ system to that of a system that utilizes unequal error protection (UEP). We show that for the AWCN channe… Show more
