Shortened turbo product codes (TPCs) have already been adopted in many standards, especially in multimedia field. Generally, the realizations of shortening turbo codes are based on designing specific interleavers with variable interleaving span; or using shortened–extended Hamming codes as the component to obtain different encoding block sizes. In this paper, we propose a very simple method to realize the shortening. This method is based on a parallel concatenated convolutional code (PCCC) and their inherent characteristic of unequal error protection. Sample simulation results are presented confirming the efficiency of the proposed scheme.
