Optimal detection and error exponents for hidden multi-state processes via random duration model approach
Dragana Bajović, Kanghang He, Lina Stanković +2
We study detection of random signals corrupted by noise that over time switch their values (states) from a finite set of possible values, where the switchings occur at unknown poin…
