Paper Abstract

JPEG is a widely used standard for coding still images. The JPEG standard is very sensitive to transmission errors and can be employed successfully only when the transmission channel is almost error-free. Wireless communication channels are characterized by long bursts of data errors and average bit error rates of 10-3 - 10-4 are typical in cellular mobile radio channels. In this paper we present an efficient scheme to transmit JPEG images over wireless channels. Also considered are post-processing techniques for error- concealment of JPEG images transmitted over these wireless channels. The effectiveness of these postprocessing techniques is demonstrated for a diverse set of images obtained from indoor radio channel experiments.
