Claim 8:
9. A method for processing a desired signal by a wireless, satellite communication terminal, comprising:
receiving signals with an antenna array having a plurality of m antenna elements arranged linearly and displaced from one another such that the displacement between each pair of adjacent antenna elements within the antenna array is substantially equal, wherein m is a number representing the plurality of antenna elements, and wherein each of the antenna elements include transmit/receive modules;
accessing a first set of complex weights to be applied to the signals received by m-1 of the antenna elements;
applying the first set of complex weights to the signals received by the m-1 antenna elements to generate complex-weighted versions of the corresponding signals received by the m-1 antenna elements;
for each pair of adjacent antenna elements within the antenna array, combining the signal received by a first one of the pair of adjacent antenna elements with the complex-weighted version of the signal received by the second one of the pair of adjacent antenna elements to generate m-1 output signals;
accessing a second set of complex weights to apply to the output signals;
applying the second set of complex weights to the output signals to generate complex-weighted versions of the output signals;
combining the complex-weighted versions of the output signals to generate an interference-mitigated output signal; and
wherein the signals received by the antenna elements, the complex-weighted versions of the signals received by the antenna elements, the output signals generated by the first-stage signal combiners, the complex-weighted versions of the output signals, and the interference-mitigated output signal for the antenna array all are RF signals.
