Notes/Equations
- This model is used to measure the bit error rate (BER) and frame error rate (FER) of the input data streams.
Each firing, one BER token and one FER token are produced when L tokens of in1 and L tokens of in2 are consumed.
The following figure illustrates the BER measurement window. Data frames from the two inputs are compared:
thene0 is the total error number of the current data frame f0
e1 is the total error number of the previous data frame f1
eWb−1 is the total error number of the earliest data frame in the BER measurement window fWb−1, and so on.
