Abstract
The capability of QC-SC-LDPC codes to be employed in broadcasting systems has been studied in previous research. However, the implementation-oriented features such as rate-compatibility and length-scalability for QC-SC-LDPC codes have not been well studied yet. In this paper, we first propose a new implementation-oriented structure of QC-SC-LDPC codes for broadcasting systems, with support for rate-compatibility and length-scalability. Then, the three-dimensional (3D-) grid-based (G-) progressive edge growth and lifting (PEGL) method is proposed to construct QC-SC-LDPC codes with that structure, which can achieve desirable performance across different code rates and code lengths within the given design complexity. Finally, a family of rate-compatible length-scalable QC-SC-LDPC codes are constructed via the 3D-G-PEGL method, and simulation results demonstrate the effectiveness of that method. Furthermore, the scaling behaviors of QC-SC-LDPC codes are observed from the provided simulation results.
期刊介绍:
The Society’s Field of Interest is “Devices, equipment, techniques and systems related to broadcast technology, including the production, distribution, transmission, and propagation aspects.” In addition to this formal FOI statement, which is used to provide guidance to the Publications Committee in the selection of content, the AdCom has further resolved that “broadcast systems includes all aspects of transmission, propagation, and reception.”
