Image and Video Transmission over Wireless Channel: A Subband Modulation Approach

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 to achieve high compression eficiency and preferable quality. Further performance gain is obtained by multiresolution modulation and bits re-mapping scheme that assign eficient mapping from source codeword to channel modulation points. The bits re-mapping scheme performs nearly same as the optimal mapping design scheme [3] but with much lower complexaty. The simulation is carried out on Additive White Gaussian Noise (AWGN) channel, and extended to the slow Rayleigh fading channel.
