TABLE V THE OUTPUT OF THE 2-LD SYSTEM EMPLOYING DEPENDENT RANDOMIZATION WHEN THE DFC LOST SYNCHRONIZATION WITH THE LDS GROUP BEFORE AND AFTER A CORRECTIVE ACTION IS TAKEN

TABLE VI THE OUTPUT OF THE 3-LD SYSTEM EMPLOYING DEPENDENT RANDOMIZATION WHEN THE DFC LOST SYNCHRONIZATION WITH THE LDS GROUP BEFORE AND AFTER A CORRECTIVE ACTION IS TAKEN

Fig.9. Zooming in on the ROC curve of the 2-LD system employing dependent randomization.

B. Numerical examples

1) 2-LD System: The design input and output of the 2-LD system employing dependent randomization with α=0.2009 was shown in Table II. When the DFC lost synchronization with the LDs group in the 2-LD system employing dependent randomization, the input and output of the redesigned algorithm are shown in Table V and Fig.8. Before the loss of synchronization the system operated at C=(0.2009,0.8261)(Table II). After the loss of synchronization the system operates at C∗=(0.2009,0.7005).

2) 3-LD System: The design input and output of the 3-LD system employing dependent randomization with α=0.1708 was shown in Table III. When the DFC lost synchronization with the LDs group in the 3-LD system employing dependent randomization, the input and output of the redesigned algorithm are shown in Table VI and Fig.10. Before the loss of synchronization the system operated at C=(0.1708,0.8448)(Table II). After the loss of synchronization the system operates at C∗=(0.1708,0.7974).
