Abstract
Embodiments of a receiver impairment estimation and correction system and method that can be implemented in a low intermediate frequency receiver system are disclosed. In one embodiment, among others, a method for operating a receiver is disclosed that comprises receiving a radio frequency signal, downconverting the radio frequency signal to a downconverted signal comprising an in-phase component and quadrature-phase component, buffering the downconverted signal in a memory, estimating receiver impairments associated with the in-phase component and the quadrature-phase component for a defined time period, and compensating for the receiver impairments for each defined time period.
