Abstract:
In one implementation, a wireless communication terminal includes a primary antenna array and a first controller configured to steer a main beam of the primary antenna array in a desired direction. The wireless communication terminal also includes an auxiliary antenna array and a second controller configured to control complex weights to be applied by at least some antenna elements of the auxiliary antenna array to corresponding variants of a second signal received by the at least some auxiliary antenna elements. Furthermore, the wireless communication terminal includes at least one signal combiner configured to combine variants of the second signal received from auxiliary antenna elements into an interfering signal that models interference from a co-located wireless communication terminal and subtract the interfering signal from variants of the first signal received from antenna elements of the principal antenna array to produce an interference mitigated signal.

Claim (Index 1):
A satellite communication terminal for transmitting signals to and receiving signals from one or more satellites orbiting the earth, the satellite communication terminal comprising:\n a steerable primary antenna that includes an array of a first number of primary antenna elements, each primary antenna element having a band pass filter configured to pass frequencies of a signal received by the primary antenna element that are within a desired frequency band while attenuating frequencies that are outside of the desired frequency band, a low noise amplifier configured to amplify a signal received by the primary antenna element, a power amplifier configured to amplify a signal to be transmitted by the primary antenna element, a switch configured to switch the primary antenna element between operating in a transmit mode and a receive mode, and a phase shifter configured to apply weights to signals transmitted and received by the primary antenna element; an auxiliary antenna having an array of a second number of auxiliary antenna elements that is less than the first number of antenna elements and a receive gain that is less than a receive gain of the steerable primary antenna, each auxiliary antenna element having a phase shifter configured to apply weights to signals received by the auxiliary antenna element; one or more controllers configured to:\n control the weights applied by the phase shifters of the primary antenna elements to steer a main beam of the primary antenna to facilitate transmitting signals to and receiving signals from the one or more satellites, and \n control the weights applied by the phase shifters of the auxiliary antenna elements in a coordinated fashion with the weights applied by the phase shifters of the primary antenna elements to facilitate reception by the auxiliary antenna of interference that also is received in a side lobe of the antenna pattern of the steerable primary antenna, the interference being caused by transmissions from a transmitter transmitting signals to a different satellite, and being higher power than the signals to be received by the satellite communication terminal from the one or more satellites; and \n one or more signal combiners configured to combine output from the primary antenna elements of the steerable primary antenna and the auxiliary antenna elements of the auxiliary antenna to generate an interference-adjusted received signal.
