Design of improved error-rate sliding window decoder for SC-LDPC codes: reliable termination and channel value reuse
《Optoelectronics Letters》2025年第4期212-217,共6页JIA Xishan LI Jining YAO Yuan WANG Yifan LIU Bo XU Degang 
supported by the National Natural Science Foundation of China (No.62275193)。
In this paper,an improved error-rate sliding window decoder is proposed for spatially coupled low-density parity-check(SC-LDPC)codes.For the conventional sliding window decoder,the message retention mechanism causes u...

Application of LDPC codes in atmospheric optical communication with coherent detection被引量：1
《Optoelectronics Letters》2013年第2期132-134,共3页陶金晶 张阳安 黄永清 张锦南 袁学光 李宇鹏 
supported by the Fundamental Research Funds for the Central Universities (No.2009RC0401);the Young Scholar Innovation Project (Nos.2011PTB-00-31, 2012RC0407 and 2012RC0406)
A novel scheme employing low-density parity-check (LDPC) codes in atmospheric optical communication system is proposed. We deploy coherent detection at the receiving side in the proposed scheme. To reduce bit error ra...
