Analysis of unequal error protection for LDPCA codes
Yuze Sun, Weu-Tek Tsai · Electronics Letters · 2013
Unequal error protection extensions of low density parity check accumulate (UEP‐LDPCA) codes are discussed and several potential applications are proposed. Two UEP‐LDPCA schemes are analysed and code parameters are optimised using a density evolution algorithm. Simulation results show that the extensions have the significant unequal error protection property. This activates new directions for existing applications.
