Abstract: A method may receive, from a dual-polarized antenna, first polarization data from a first channel and second polarization data from a second channel having a polarization orientation that is different from the first channel, the first and second polarization data representing signal from a noise source including randomly polarized noise. A method may generate filtered first polarization data by filtering data from the first polarization data that is more than a predetermined distance from a first polarization data mean. A method may generate filtered second polarization data by filtering data from the second polarization data that is more than the predetermined distance from a second polarization data mean. A method may determine a tilt polarity mismatch and an ellipticity polarity mismatch based on the filtered first polarization data and the filtered second polarization data.

Abstract: A system and method to perform post pass optimizations in a dynamic compiling environment. A dynamic compiler emits machine code. Responsive to the emission of the machine code a post pass processor creates an abstract representation of the code from the dynamic compiler. Data flow analysis is then conducted on the abstract representation. Redundant instructions in the machine code are identified and eliminated as a result of the data flow analysis.
