Abstract

In this letter, we propose a segmented CRC-aided spinal code (SCA-spinal code) where an encoding structure is designed based on a novel sliding window decoding algorithm. The proposed algorithm reduces the decoding computation significantly by terminating the decoding process earlier when the segment decoding results fail to pass the corresponding CRC check. The decoding results are checked once a segment decoding is complete. Furthermore, we propose a transmission strategy after the decoding process fails to save the transmitting symbols and therefore improve the spectral efficiency. The numerical results show that our proposed SCA-spinal code reduces decoding complexity and improves spectral efficiency.
