Abstract
Systems and methods for adjusting phase of a signal are provided. In one embodiment, the system includes a phase compensator configured for adjusting phase of the signal based on filtered and unfiltered representations of a first component of the signal and based on filtered and unfiltered representations of a second component of the signal. For example, the phase compensator may provide phase adjusted I and Q components of a complex signal through a plurality of multiplications of filtered and unfiltered I and Q components. The system also includes a detector that is communicatively coupled to the phase compensator. The detector is configured for combining the first and the second components with a code sequence to determine a complex amplitude of a channel.
