BERT PRN: the data are generated from pseudo-noise sequence. The generator
polynomial is selected by the parameter PRN generator polynomial degree, according to
the following table. The vector of initial states is in every case at the value 1. The sequence
polynomial degree
length is (2
)-1.
The BER is measured by processing with the same polynomial the data received by the
Telemetry Unit selected owing to the parameter TM Flow for BER. The TMU Frame
Synchronizer has to be disabled.
