| Summary: | Abstract The recently introduced spatially coupled turbo‐like codes are attractive in trading‐off performances between the error‐floor region and the water‐fall region. This letter is concerned with the construction of spatially coupled serially concatenated codes. Particularly, a new construction of spatially coupled serially concatenated codes is presented, in which a portion of the encoding output of the previous inner encoder is taken as the input of the current inner encoder. The authors show that by proper selection of the component codes and the re‐encoding ratio, performance gain about 0.25 dB is obtained with the proposed construction. |
