IEEE/ICACT20210117 Question.4 Questioner: zhanyueying@csu.ac.cn 2021-02-10 오전 12:23:24	IEEE/ICACT20210117 Answer.4 Answer by Auhor gueye.ibrahima1@esp.sn 2021-02-10 오전 12:23:24
Thank you for your presentation. In your opinion, what features of GC-LDPC codes make their performance better than other LDPC codes in mixed RF/FSO transmission?	Thanks for your question. GC-LDPC codes are structured LDPC codes, yet structured LDPCs give better performance compared to linear block LDPC codes. A GC-LDPC code is made up of several LDPC codes that are smaller blocks. The highly structural code construction facilitates efficient implementation while maintaining compelling error correction capabilities of large block length codes. A GC-LDPC code is an LDPC code made up of several LDPC codes of shorter block length, called local codes. So in terms of performance in RF / FSO transmission, GC-LDPC codes give better performance compared to LDPC codes
