Unequal Error Protected Image Transmission over Multilevel coded Wavelet Packet Multicarrier Modulation System

Unequal error protection (UEP) is applied in image transmission with the nonuniform signal constellation design over multilevel coded wavelet packet multicarrier modulation (MLC-WP-MCM) system. Different data division schemes are analyzed and compared. Simulation results show that image transmission by UEP with bit-based data division scheme presents much higher PSNR values and surprisingly better image quality in our proposed system
