1. A method for providing Multi-Input Multi-Output (MIMO) feeder links for a multibeam satellite, the method comprising:
receiving a Tx signal as X Tx signals on a MIMO channel with Y-antennae as Y Rx signals, wherein each of the Y-antennae generate one of the Y Rx signals; and
ground-interference processing the X Tx signals or the Y Rx signals to recover the Tx signal,
wherein
when the Y-antennae are not disposed on a ground, pre-interference processing the X Tx signals and post-interference processing the Y Rx signals as a pass through when a respective Signal-to-Interference-and-Noise Ratio (SINR) of each of the Y Rx signals is greater than a threshold, and
when the Y-antennae are disposed on the ground, pre-interference processing the X Tx signals as a pass through and post-interference processing the Y Rx signals when a respective Signal-to-Interference-and-Noise Ratio (SINR) of each of the Y Rx signals is greater than a threshold, and
a channel capacity of the MIMO channel is greater than a channel capacity of a Single-Input Single-Output (SISO) channel having resources identical to the MIMO channel.
