The propagation grandpas best of a millimeter wave (mmWave) signal is dominated by its line-of-sight component.Therefore, the knowledge of angle-of-arrival and polarization state of the wave is of great importance for its reception at the receiver.In this paper, we estimate these parameters for an information-bearing signal in mmWave systems using hybrid antenna arrays with dual-polarized dipoles.The estimation is studied in the context of both the interleaved and localized arrays.

Two blind adaptive algorithms, namely, the joint differential beam tracking and cross-correlation-to-power ratio polarization tracking, and the differential beam and polarization search, are developed, each tailored for an array.It is shown that the use of dual-polarized dipoles in combination with the bushranger awning developed algorithms effectively lead to polarization diversity which significantly enhances the signal-to-noise ratio at the decoder.The simulation results also show that the antennas with dual dipoles provide improved accuracy and convergence rate for the estimations compared with the conventional arrays.
