Abstract:
A method for determining the polarization of a received signal that has two orthogonal components comprising:(a) combining said orthogonal components with one another according to a plurality of different combining schemes each having different values of characteristic variables to produce a plurality of output signal sets, each one of said output signal sets including one or more output signal sets produced according to one of said plurality of different combining schemes, two or more of said different combining schemes being applied substantially simultaneously to produce two or more of said sets of output signals substantially simultaneously; (b) measuring one or more parameters of each said set of output signals; and (c) comparing said measured parameters so as to select one said set of output signals which best meets one or more predetermined criteria and thereby select the combining scheme associated with the selected set of output signals, whereby selection of said combining scheme implicitly selects an estimate of the polarization of the received signal.
