Abstract
A receiver that includes a carrier recovery module that includes a reference signal generator that is arranged to generate a reference signal that estimates a carrier signal; a decision module that is arranged to demodulate a receiver input signal by the reference signal to provide a demodulated signal and to evaluate the demodulated signal to provide an decision module output signal that estimates the carrier signal; the reference signal generator includes a delay and rotation module that is arranged to delay receiver input signals to provide delayed receiver input signals and to align the delayed receiver input signals by a rotation that is responsive to the decision module output signal thereby providing aligned signals; and a multiplication and summation module that is arranged to generate the reference signal by calculating a weighted sum of the aligned signals.
