Abstract:
A circuit for canceling cross polarization interference has a first signal input and a second signal input. An adjustable cancellation network circuit is coupled to the first input and the second input. The adjustable cancellation network circuit has a first programmable vector modulator having a first weight and a second programmable vector modulator having a second weight. The first weight is correlated to the first input signal to obtain a first output signal. The second weight is correlated with the second input signal to obtain a second output signal. A performance measurement circuit is coupled to the cancellation network circuit and receives the first output signal and the second output signal. The performance measurement circuit generates a first correlated signal corresponding to the amount of interference in the first correlated signal and a second correlated signal corresponding to the amount of interference in the second correlation signal. A controller is coupled to the cancellation network and performance measurement circuit.
