Abstract
An example of a radio frequency (RF) receiver system for communication may include a receive channel frequency converter configured to provide a second receive calibration signal during a receive calibration mode based on a first receive calibration signal and a receive reference signal. The system may include a receive pre-distortion module coupled to the receive channel frequency converter. The receive pre-distortion module may be configured to provide a fourth receive calibration signal during the receive calibration mode based on a third receive calibration signal and one or more receive calibration adjustment signals. The one or more receive calibration adjustment signals may comprise an offset parameter associated with DC offset and an imbalance parameter associated with at least one of gain and phase imbalances.
