In this paper, we present a new proposed error concealment algorithm toimprove the image quality degraded during its transmission over wireless channel.Different error concealment strategies are applied to different locations of blocks inorder to achieve better visual quality. The proposed algorithm conceal the lost blockusing Framelet Transform (FT), this is achieved by finding the average of frameletsubbands in neighbors of the lost block. Finally, the results of this algorithm comparedwith the results of MultiWavelet Averaging (MWA) algorithm in terms of signal tonoise ratio (SNR) and human vision.
