Receive Signal Oversampling
In order to additionally reduce the bit error rate in severe conditions, the OCTAT-P
performs oversampling of the received signal and uses majority decision logic. As
illustrated in figure 13, each received bit is sampled 6 times at 15.36 MHz clock intervals
inside the estimated bit window. The samples obtained are compared against a
threshold of 50 % with respect to the signal stored by the peak detector. If at least 4
samples have an amplitude exceeding the 50 % threshold, a logical “1” is considered to
be detected; otherwise a logical “0” (no signal) is considered to be detected
.
