Beam to beam coupling cancellation

A method for beam-to-beam (B2B) coupling cancellation, the method comprising:

• obtaining, at a first FE of a serially fed FE network, a first RF signal and a second RF signal, wherein:
• the first RF signal is coupled to a first signal path of the first FE;
• the first RF signal comprises a first data beam;
• the first RF signal is coupled to a second signal path of the first FE for the second RF signal by a cross-coupling between the first signal path of the first FE and the second signal path of the first FE, wherein the cross-coupling between the first signal path of the first FE and the second signal path of the first FE generates a coupling component;
• the second RF signal is coupled to the second signal path of the first FE;
• and
• the second RF signal comprises a second data beam;
• outputting, from the first FE, a first through path RF signal based on the first RF signal and a second through path RF signal based on the second RF signal;
• obtaining, at a second FE of the serially fed FE network, the first through path RF signal and the second through path RF signal;
• and
• applying one or more phase shifts to the first RF signal, the second RF signal, the first through path RF signal, or the second through path RF signal to at least partially cancel the coupling component associated with the cross-coupling between the first signal path of the first FE and the second signal path of the first FE.
