Abstract
Satellite communication methods and payloads are described. The payload and methods are designed to enable effective use of carrier signals in the guard band region of a channelized band of spectrum. An on-board digital channelizer may implement a band edge power monitor for measuring power spectral density in the band edges of a channel and, if it exceeds a preset threshold level, downscaling the signal amplitude in the band edges to prevent hardware damage to the payload. The channelizer may further implement a band edge gain adjustment filter for shaping the overall frequency response to flatten the response across adjacent channels, including through the guard band region between the passbands of the adjacent channels.
