Bit Synchronization - Safran CORTEX Series User Manual

Please note that for link budget with actual satellite that implementation loss doesn't take into account
imperfections of:
on board modulator RF and antenna Multipath non-linearity ...
-
non Gaussian transmission imperfection weather...
-
- ground imperfection: pointing accuracy RF & feed..
And for transmission above 300Mbps all those imperfections become critical.
Cortex DEAF and/or XDEAF will correct all those imperfections with residual loss from 0.1 to 1dB.
