Abstract: Techniques described herein provide cancelation of cross-polarization interference during simultaneous receipt of radiofrequency signals (e.g., an X-signal and a Y-signal) in a same frequency channel in nominally orthogonal polarizations. Though nominally orthogonally polarized, each signal contributes some cross-polarization interference to the other. Embodiments receive and demodulate each signal by a corresponding demodulator to generate corresponding X-symbol and Y-symbol decision signals, referenced to a common clock domain. An X-channel adaptive canceler (X-CAC) generates an X-output signal by using one or more Y-symbol decision signals adaptively to cancel cross-polarization interference from the Y-signal, and a Y-CAC generates a Y-output signal by using one or more X-symbol decision signals adaptively to cancel cross-polarization interference from the X-signal (e.g., the X-CAC and the Y-CAC each using a first-order least mean squares control loop).

Abstract: Systems and methods for aligning timing of an inroute transmission of a terminal with a gateway are disclosed. A system may include a processor and a memory storing instructions, which when executed by the processor, may cause the processor to perform a random estimation of location pertaining to a time-division multiple access (TDMA) frame boundary of a gateway. Based on an asynchronous scrambled coded multiple access (ASCMA) technique, the system may transmit ASCMA group burst packets including precise timing feedback request for the gateway. The system may receive a feedback from the gateway, in response to the precise timing feedback request. The processor may determine an adjustment for aligning timing of an inroute transmission of the terminal with respect to the TDMA frame boundary of the gateway. The system may apply the adjustment to synchronize the timing of the inroute transmission of the terminal with the gateway.
