摘要:
A method and apparatus is disclosed to compensate for an in-phase/quadrature phase (I/Q) imbalance in a communications receiver. The communications receiver may utilize information gained from observing one or more observational interferers to adjust one or more sequence parameters, such as gain and/or phase to provide some examples. The one or more observational interferers including one or more images outside of a desired frequency band of interest. The communications receiver provides one or more sequence parameter values to allow for real-time adjustment of the sequence parameters to compensate for the I/Q imbalances.
