A Newly Designed Quarter-Rate QC-LDPC Code for the Cloud Transmission System
Sung-Ik Park, Heung Mook Kim, Yiyan Wu, Jeongchang Kim · IEEE Transactions on Broadcasting · 2013
In this brief, we propose a newly designed quarter-rate quasi-cyclic low density parity check (LDPC) code for the cloud transmission system. The cloud transmission system requires a near Shannon limit low-rate coding for the next generation terrestrial digital television system. The proposed LDPC code is optimized forR=1/4. At the code length of 64 K, it is only 0.6 dB away from Shannon limit.
