We designed UEP Turbo and LDPC codes based on puncturing and pruning. In Turbo codes, pruning and puncturing with time-varying patterns allow for easy variation of the rate and gain. UEP LDPC codes were designed based on a irregular check profile. The applied pruning procedure allowed rate and gain adaptation according to given requirements.
UEP coded modulation is designed following the capacities at different partition levels at different signal-to-noise ratios.
