Multilevel codes for unequal error protection


Journal Article

In many speech and image coding schemes, some of the coded bits are extremely sensitive to channel errors while some others exhibit very little sensitivity. In order to make the best use of channel redundancy, unequal error protection (UEP) codes are needed. In a bandlimited environment, such coding and the modulation should be integrated. In this paper, the authors propose two combined UEP coding and modulation schemes.
