This paper investigates the performance of image transmission with unequal error protection (UEP) through typical satellite communication channel, and the UEP is achieved by mapping different bits of the image bytes to different positions of a progressive edge growth (PEG) constructed irregular Low-Density Parity-Check (LDPC) codes. The satellite communication channel consists of two main fading: one is the nonlinearity caused by on-board high power amplifier (HPA), and another is the time-varying fading caused by the propagation channel, a neural network (NN) based predistortion technique is adopted to deal with the nonlinearity.
