    Abstract: A method in a receiver node (110, 115) is disclosed. The method comprises converting (604) a received time-domain signal (305, 405) to a frequency-domain signal, and obtaining (608), for the frequency-domain signal, an estimate of a frequency offset between a particular transmitter of one or more transmitters of interest and a receiver of the receiver node. The method comprises obtaining (612) a frequency compensated signal by applying a first frequency offset to compensate for the estimated frequency offset, and obtaining (616) a first channel estimation from the frequency compensated signal. The method comprises obtaining (620) a second channel estimation from the first channel estimation by applying a second frequency offset to the estimated channel, wherein the second frequency offset is the opposite of the first frequency offset.

    Abstract: Techniques for pilot-aided carrier frequency and phase synchronization may use a three-pass process. In a first pass, initial frequency offset may be addressed, and a frame start time may be established. In a second pass, a fine frequency correction may be performed. In a third pass, phase variation may be tracked and corrected using a minimum set of pilot symbols.

    Abstract: A method and apparatus for estimating a frequency offset of received signals. The receiving device receives a plurality of pilot signals form a transmitting device, and determines an un-aliased frequency offset estimate based on the received pilot signals. The receiving device further determines a low-noise frequency offset estimate based on the received pilot signals, wherein the low-noise frequency offset estimate is blow a threshold noise level. The receiving device then generates a hybrid frequency offset estimate based at least in part on the un-aliased and low-noise frequency offset estimates, wherein the hybrid frequency offset estimate is un-aliased and has a lower estimation noise than the un-aliased frequency offset estimate.
