Receive path in-phase and quadrature imbalance correction using circuit noise

Abstract

Example operations may include determining a first noise estimate of noise that propagates along a receive path of a device. The operations may further include determining a second noise estimate of the noise and determining a cross-relationship estimate with respect to the noise. In addition, the operations may include adjusting one or more correction filters configured to correct for imbalances between a first branch and a second branch of the receive path. The adjusting may be based on the first noise estimate, the second noise estimate, and the cross-relationship estimate.

1 . A method comprising:
 determining a first noise estimate of first noise that propagates along a first branch of a receive path of a device;   determining a second noise estimate of second noise that propagates along a second branch of the receive path;   determining a cross-relationship estimate between the first noise and the second noise; and   adjusting one or more correction filters configured to correct for imbalances associated with the first branch and the second branch of the receive path, the adjusting being based on the first noise estimate, the second noise estimate, and the cross-relationship estimate.
