1. A method of estimating a frequency offset of received signals, the method comprising: receiving a plurality of pilot signals from a transmitter; determining an un-aliased frequency offset estimate by dividing a first pilot signal of the plurality of pilot signals into two or more split-pilot signals and taking a vector cross product of the two or more split-pilot signals; determining a low-noise frequency offset estimate based on a vector cross product between the first pilot signal and a delayed first pilot signal, wherein an estimation noise of the low-noise frequency offset estimate is below a threshold noise level; and generating a hybrid frequency offset estimate based at least in part on the un-aliased frequency offset estimate and the low-noise frequency offset estimate, wherein the hybrid frequency offset estimate is un-aliased and has a lower estimation noise than the un-aliased frequency offset estimate.
