Abstract: An implicit link adaptation technique based on
hybrid automatic repeat request (H-ARQ) and soft-combining is
considered for transmission of Joint Photographic Experts Group
2000 (JPEG2000) images over wireless channels. Adaptation is
carried out utilizing an objective perceptual image quality metric
that takes into account the human perception. Retransmissions
focus on the Region of Interest (ROI) part of the JPEG2000
image to efficiently utilize the bandwidth. Numerical results show
that the combination of the proposed perceptual image quality
metric with link adaptation provides robust link performance
while meeting satisfactory quality constraints.
