By observed in Fig. 1, one can find that the BER performances of both RUEP and EWF codes, the BER of each block would monotonically decreasing as overhead increases, and the higher UEP weight or selecting probability would leading a better (lower) BER … Weboptimizing the UEP Raptor codes to minimize the cost at the server, i.e., the required transmission overhead, subject to pro-viding users with QoS guarantees. We also propose a simpler and more modular UEP Raptor code design which encodes different layers separately and is convenient to analyze. The
