Abstract :
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.
