dc.description.abstractA new approach of reliable image and video transmission over wireless channels is proposed. The subband modulation which combines source coding and channel modulation schemes achieves high compression efficiency and preferable quality. Further performance gain is obtained by multiresolution modulation and a bits re-mapping scheme that assigns efficient mapping from each source code word to channel modulation points. We show that bits re-mapping schemes perform nearly the same as the optimal mapping design scheme but with much lower complexity. The simulations are carried out on Additive White Gaussian Noise (AWGN) channels and slow Rayleigh fading channels.en_US
