20140273812 | Method for the Control of a Wireless Communications Link for Mitigating Adjacent Satellite Interference - A method for remotely and dynamically controlling adjacent satellite interference comprising monitoring one or more off-axis signals emitted by one or more remote transmitters; determining whether one or more of the off-axis signals is creating adjacent satellite interference (ASI), off axis emissions and inband interference that is higher than a predetermined level of acceptable interference, and transmitting a control signal to at least one of the one or more remote transmitters in response to the determination that the one or more off-axis signals is creating interference that is higher than the predetermined level of acceptable interference, the control signal initiating an adjustment to one or more transmission parameters of the one or more remote transmitters such that interference resulting from the one or more off-axis signals emitted by the one or more remote transmitters is reduced or eliminated. | 09-18-2014 |
20160073359 | Method and System for Controlling a Communications Carrier's Power Spectral Density (PSD) Using Spread Spectrum for Matched Spectral Allocation - A method of reducing adjacent satellite interference, the method comprising monitoring, by a processor, a power spectral density (PSD) of a signal transmitted by a remote transmitter, determining, by the processor, that the PSD of the signal transmitted by the remote transmitter is above a predetermined level, and reducing the PSD of the signal transmitted by the remote transmitter by adjusting at least one of a spread spectrum spreading factor, a power level, a modulation factor, and a forward error correction (FEC) rate using a modulator while maintaining a constant spectral allocation and center frequency of the signal. | 03-10-2016 |
