Abstract
Apparatuses, methods, and systems are disclosed for determining a composite zero-forcing equalizer. One method includes measuring a first frequency response at a first antenna connector. The method includes determining a first zero-forcing equalizer for the first antenna connector as an inverse of the first frequency response. The method includes measuring a second frequency response at a second antenna connector. The method includes determining a second zero-forcing equalizer for the second antenna connector as an inverse of the second frequency response. The method includes determining a composite zero-forcing equalizer as a normalized power weighted linear combination of absolute value magnitudes of the first zero-forcing equalizer and the second zero-forcing equalizer.
