A Two-Stage Iterative Decoding of LDPC Codes for Lowering Error Floors
Jingyu Kang, Li Guo Zhang, Zhi Jun Ding, Shu Lin · 2008
In iterative decoding of LDPC codes, trapping sets often lead to high error floors. In this work, we propose a two-stage iterative decoding to break trapping sets. Simulation results show that the error floor performance can be significantly improved with this decoding scheme.
