EN The author revises his concept of Packet Appending for Bit-Interleaved Coded Modulation with Iterative Decoding (PA-BICM-ID) and proposes a new receiver design in which some demapper operations are called in every iterative decoding pass, as previously, but the rest is called only in the first iteration, thereby reducing the computational cost. Afterwords, it is shown that PA-BICM-ID can considerably improve the performance of such systems that originally employ low-order modulation. The decoding convergence is examined by means of the EXtrinsic Information Transfer (EXIT) chart, whereas the overall system performance over uncorrelated Rayleigh fading channel is analyzed using computer simulation.
