    摘要: In a turbo decoder for code rate 1/n which consists of a decoding block, that is, n−1 constituent decoders, n−2 interleavers and n−2 deinterleavers, one embodiment of a decoding method according to the present invention comprises: a first decoding process of sequentially decoding starting from a first constituent decoder among the n−1 constituent decoders to generate a first log-likelihood ratio; a second decoding process of sequentially decoding starting from a second constituent decoder to generate a second log-likelihood ratio different from the first log-likelihood ratio, the second decoding process being activated in parallel with the first decoding process; a (n−1)th decoding process of sequentially decoding starting from a (n−1)th constituent decoder to generate a (n−1)th log-likelihood ratio different from the log-likelihood ratios, the (n−1)th decoding process being activated in parallel with other decoding processes; a step of optimally weighting respective components forming each log-likelihood ratio simultaneously generated at each decoding process; and a step of combining the weighted log-likelihood ratios and performing the hard decision using a combiner to obtain diversity gain. Another embodiment of a decoding method comprises the steps of: after adding a decoding block, activating the decoding blocks in parallel; activating the constituent decoders of each decoding block in parallel; optimally weighting components of respective log-likelihood ratios from respective decoding processes and combining the weighted log-likelihood ratios at the combiner. The present invention considerably improves a bit error rate characteristic and reduces the number of iterations required to satisfy a given bit error rate, compared with the conventional decoding method.

    摘要: Integrated circuit devices are fabricated by fabricating a conductive line on an insulating layer on an integrated circuit substrate. The conductive line includes a bottom adjacent the insulating layer, a top remote from the insulating layer and first and second sidewalls therebetween. An insulating spacer is formed to extend along the first and second sidewalls and to also extend along at least a portion of the bottom between the conductive line and the insulating layer. By providing an insulating spacer beneath at least a portion of the conductive line, insulation reliability may be improved even as the spacer may become narrower and/or the contact area may be enlarged.
