Abstract
Apparatus, systems, and methods implementing techniques for estimating a relative rotation between a first complex signal and a second complex signal. The first complex signal is quantized to produce a quantized signal, and the quantized signal and an additional signal are combined, where the additional signal corresponds to the second complex signal. An estimate of a relative rotation between the first complex signal and the second complex signal is generated in accordance with the combined signal.
