Abstract :
The Luby Transform (LT) codes have been suggested as an efficient solution for multimedia communications over erasure packet network, and provide equal error protection (EEP) for all input symbols. However, for the progressive image transmission, the significant source bits are generally located ahead of the bit streams of the encoder output, which are more important for the reconstruction of the image. Therefore, the LT codes based on EEP (EEP-LT) scheme is not suitable for the progressive image transmission. In the paper, based on the LT codes, a novel unequal error protection (UEP) scheme is proposed for image transmission over multiple input multiple output (MIMO) channels, which is named UEP-LT scheme. Simulation results confirm the efficiency of the proposed scheme.
