Abstract
A gateway uplink to a satellite may use cross-polarization interference cancellation (XPIC). The uplink may utilize two frequencies, each using XPIC. Data may be transferred by these four avenues: two polarizations and two frequencies. Onboard the satellite, radio-frequency front end hardware detects the signal and produces as output in-phase (I) and quadrature (Q) data for each frequency and polarization. First IQ data is processed by a first pair of modems and second IQ data is processed by a second pair of modems. Each pair of modems processes the respective IQ data to implement XPIC. The first pair is connected to a network processor. The second pair is daisy-chained via the first pair to the network processor. During a failure in the second pair, XPIC ceases and connections previously used to exchange IQ data are used to transfer network data between the second pair and then to the network processor.
