Abstract: Labeling maps affecting the performance of bitinterleaved coded modulation with iterative decoding (BICMID) system were investigated, and a new labeling map called the defined region optimum symbol map (DRO), which satisfies performance requirement in a given SNR region, was proposed. By systematic research of the characteristic parameters of various labeling maps and analysis of the asymptotic performance of the iterative decoding system, key parameters to decide the performance of the BICMID system were obtained when convolutional codes were used as error correction codes.
