Patent abstract

Frequency offsets between a received carrier signal and a receiver's LO frequency are compensated by determining the offset and adjusting the phase of a demodulated signal derived from the modulated carrier. For frequency offsets that produce DC voltage offsets in I and Q components of the demodulated signal, the phase correction is implemented by operating upon the I and Q components with phase rotation operators in the form of sin θ and cos θ, where θ is an angle whose tangent is the result of dividing the Q by the I frequency offsets.
