PB: A Product-Bitmatrix Construction to Reduce the Complexity of XOR Operations of PM-MSR and PM-MBR Codes over

Figure 8

The number of XORs of PB-MSR and PB-MBR. The original PB-MSR and PB-MBR are the baselines represented by the line chart. The optimized PB-MSR and PB-MBR are represented by the bar graph.
