Figure 12From: Techniques and Architectures for Hazard-Free Semi-Parallel Decoding of LDPC Codes An example of optimization of the base-matrix of the LDPC code IEEE 802. 11n with and with EOP, ROP and UOP. Critical propagations are highlighted in dark gray.Original base-matrix (sequence of layers: 0,1,2,3,4,5,6,7)EOP (optimised sequence of layers: 0,5,6,7,4,2,3,1)ROP (optimised sequence of layers: 0,2,7,5,6,3,4,1)UOP (optimised sequence of layers: 0,4,7,6,1,2,6,3)Back to article page
