Abstract :
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
