Title: PHASE-COMPENSATING POLARIZATION DIVERSITY RECEIVER
Abstract:
A receiver and an associated method are disclosed for combining signals having substantially different polarizations. The receiver is used with a first antenna which receives first polarized signals and a second antenna which receives second polarized signals, the first polarized signals having a substantially different polarization than the second polarized signals. The receiver includes a phase shifter and a combiner circuit. The phase shifter adjusts the phase of the first polarized signal in response to the phase of the second polarized signal to produce a phase compensated first signal. The combiner circuit sums the second polarized signal and the phase compensated first signal to generate a combined polarization received signal. In this manner, the depolarized signals are phase-aligned with, and then combined with, the polarized signals to provide a strong received signal irrespective of any depolarization of the received signal.
