摘要

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.
