3.2.3 Rx Baseband Processing
The Receive Processor performs the inverse function of the Transmit Processor. Data received
from the satellite passes through the BB Loopback Circuit to the R-S decoder to the deframer.
The deframer acquires the IBS/IDR/DVB frame, synchronizes the R-S decoder, and extracts the
received data and overhead from the frame structure. It puts the data into the PD buffer, sending
the overhead data to the UIM. The data is extracted from the buffer and is sent to the UIM.
Backward Alarm indications are sent to the M&C Subsystem.
