Finding optimal decision threshold for binary comm system
  1. How do you calculate decision threshold?
  2. What is the decision threshold in optimum filter?

How do you calculate decision threshold?

A simple formula to determine the optimal decision threshold (Zweig & Campbell, 1993) maximizes: Sensitivity - m * (1- Specificity) where m = (Cost FP - Cost TN) / (Cost FN - Cost TP).

What is the decision threshold in optimum filter?

The decision threshold defines the signal state at which the comparator(s) for that axis makes the decision that the bit represents one value or the other.
