A channel quality based unequal error protection (UEP) method for wireless video transmission is proposed in this paper. The importance of different partitions of the compressed video bitstream is classified by the corresponding impact on the decoding quality, and has been taken into consideration in designing the transmission system. In order to avoid mapping the important parts into the subcarrier in deep fading, a subcarrier mapping rule combined with the hierarchical QAM (HQAM) is also proposed. Simulation results demonstrate that the proposed UEP method outperforms the equal error protection method (EEP) and the previously developed UEP methods by an average improvement of the received video of 4.0 dB.
