Abstract
A communication platform such as a spacecraft, airborne platform, or terrestrial line of site wireless platform is provided with adaptive digital beamforming. The satellite digitizes a full spectrum allocation for digital channelization. A channelization engine can determine a particular user or user group associated with an uplink signal. In this manner, the communication platform can apply different processing based on the user or group associated with a signal. For example, the communication platform receives uplink signals associated with a first user group and a second user group in one embodiment. The platform dynamically generates one or more spot beams for the first user group and the second group. The platform discriminates the uplink signals to apply frequency hopping for the downlink frequency channel assignments to the second user group while the downlink frequency channel assignments for the first user group remain fixed.
