If the dRSS signal is above the sensitivity floor, it is counted as qualifying snapshot and if then the composite iRSS signal satisfies the criteria (e.g. if dRSS-iRSS>C/I), then the system notes that the given snapshot produced the non-interfered communication attempt.
SEAMCAT calculates the probability of interference (pI) of the victim link receiver as follows:
P_I=1-P_NI (Eq. 74)
were pNI is the probability of Non Interference (NI) of the receiver.
When a C/I criterion is considered, pNI is defined as:
(Eq. 75)
since by definition P(A|B)=P(A∩B)/P(B), pNI becomes:
(Eq. 76)
with 
where P is the number of interferers (i.e. active transmitters).
Monte Carlo method is applied individually to the numerator and to the denominator of the expression of pNI . The result obtained is an estimation of pNI by using the following equations (p’NI):
(Eq. 77)
with M the number of events (or snapshots) and where
(Eq. 78)
Similarly, when a C/(I+N) criterion is considered, pNI is defined as:
(Eq. 79)
When a (I+N)/N criterion is considered, pNI is defined as:
(Eq. 80)
When a I/N criterion is considered, pNI is defined as:
(Eq. 81)
