System and method for in-phase/quadrature-phase (I/Q) time delay measurement and compensation
Abstract:
A system for determining a time delay between an in-phase signal component and a quadrature-phase signal component includes an in-phase signal start time determination module coupled to an in-phase delay module, the in-phase signal start time determination module and the in-phase delay module configured to receive an in-phase signal component of a received signal. The in-phase signal start time determination module is configured to receive a reference signal. The system also includes a quadrature-phase signal start time determination module coupled to a quadrature-phase delay module, the quadrature-phase signal start time determination module and the quadrature-phase delay module configured to receive a quadrature-phase signal component of a received signal. The quadrature-phase signal start time determination module is configured to receive a reference signal, wherein the in-phase delay module is configured to develop an in-phase delay signal and the quadrature-phase delay module is configured to develop a quadrature-phase delay signal.
