The propagation of a millimeter SIEMENS iQ700 LC91KWW69B - 90cm Wall-mounted cooker hood - Black Glass 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 Horn Bags dipoles in combination with the 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.
