In order to additionally reduce the bit error rate in severe conditions, the ISAC-S TE performs
oversampling of the received signal and uses majority decision logic.
As illustrated in figure 27, each received bit is sampled 29 times at 7.68-MHz clock intervals
inside the estimated bit window. The samples obtained are compared against a threshold
VTR1 or VTR2 (see section: Adaptive Receiver Characteristics).
If at least 16 samples have an amplitude exceeding the selected threshold, a logical "0" is
considered to be detected, otherwise a logical "1" (no signal) is considered detected.
