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.

Abstract: A communications waveform schema integrates security at the physical layer and has many desirable features of traditional LPI/LPD waveforms. To provide additional covert aspects in communications a single-carrier base waveform is divided up in frequency and/or time and redistributed pseudo-randomly among subcarriers and channel assignment. Multiple matched polyphase filterbank channelizers are used so that each individual channel has a bandwidth well below a Nyquist rate for information carried by the base waveform, thereby making full data extraction from any individual channels a theoretic impossibility. The individual channels do not carry enough information from the base waveform to be useful and only in the aggregate can the entire base waveform be reconstructed. Individual channels are up-converted onto pseudo-randomly chosen carrier frequencies within the bandwidth of the high rate hardware IF in such a way as to obfuscate the order in which they occur in the base waveform.
