Wireless communication with interference mitigation

A method for processing a desired signal by a wireless communication terminal mounted on a common surface with a co-located interfering wireless communication terminal comprising:

• receiving a main signal with at least one primary antenna of the wireless communication terminal, the main signal including interference from a proximally located interfering wireless communication terminal transmitting an interference signal, the at least one primary antenna having a first polarization type;
• sampling the interference signal from the interfering wireless communication terminal with a sense antenna of the wireless communication, the sense antenna having a second polarization type, substantially orthogonal to the first polarization type of the at least one primary antenna, wherein the wireless communication terminal is mounted to a same surface as the interfering wireless communication terminal;
• and
• combining a version of the sampled interference signal with a version of the main signal to produce an interference mitigated signal.

A satellite communication terminal for mounting on a common surface with a co-located interfering communication system terminal, comprising:

• a sense antenna configured to be oriented towards a co-located interfering communication system terminal mounted on a common surface with the satellite communication terminal and to sample an interference signal from the interfering communication system terminal, wherein the sense antenna has a first circular polarization type;
• a primary antenna array including a first number of primary antenna elements, the primary antenna array being configured to receive a desired signal, each of the primary antenna elements having a second circular polarization type, orthogonal to the first circular polarization type of the sense antenna;
• and
• at least one signal combiner configured to receive output of the sense antenna and output of the primary antenna array, and configured to mitigate interference with the desired signal by combining a version of the output of the sense antenna with a version of the output of the primary antenna array to produce an interference mitigated signal.
