چکیده
A new approach of reliable image and video transmission over noisy channel is proposed. The proposed subband modulation scheme combines source coding and channel modulation scheme t o achieve high compression ef ic iency and preferable quality. Further performance gain is obtained by multiresolution modulat ion and bits re-mapping scheme that assign e f i c i en t mapping f rom source codeword t o channel modulation points. T h e bits re-mapping scheme performs nearly same as the optimal mapping design scheme [3] but with much lower complexaty. T h e simulation is carried out o n Additive White Gaussian Noise (AWGN) channel, and extended t o the slow Rayleigh fading channel.

A New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks
The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...
