no code implementations • r, IEEE Dept. of Communication Engineering 2013 • Liangliang Xu, Huihui Wu, Jiguang He and Lin Wang, Senior Member

In this paper, a novel unequal error protection (UEP) scheme, which is constructed from protograph double low-density parity-check (PD-LDPC) codes, and tailored for medical images is proposed to minimize the end to end image distortion over additive white Gaussian noise (AWGN) channel.
