WebDec 16, 2015 · In multimedia communications and different other areas, it is desired that channel codes can provide the property of unequal error protection (UEP). In this paper, we study two methods to provide UEP Raptor codes on the binary erasure channel (BEC): (1) Using UEP precode (2) Using UEP LT codes. Webof Raptor codes with both UEP and systematic properties over BEC. The proposed Raptor codes consist of an UEP-LDPC code and an UEP-LT code. Numerical results show that the proposed design is effective for reliable multi-level protection. The rest of the paper is organized as follows. Section 2 reviews systematic EEP-Raptor codes and ...
