Abstract: A method includes obtaining a first single-ended measurement signal and a second single-ended measurement signal; and producing an equalized measurement signal at least partially based on a predetermined pseudoinverse channel matrix and one or more of: the first single-ended measurement signal and the second single-ended measurement signal.

Abstract: In one embodiment, a method of compensating for retransmission effects in a touch sensor includes, in response to measuring a touch input on a display, generating a first matrix comprising a plurality of first measurements associated with a plurality of capacitive nodes of a touch sensor. The method also includes estimating an amount of retransmission associated with the touch input by generating a first vector comprising one or more second measurements associated with one or more first electrode lines of the touch sensor, generating a second vector comprising one or more third measurements associated with one or more second electrode lines of the touch sensor, and calculating an outer product of the first and second vectors. The method includes generating a revised indication of the touch input based on the first matrix and the estimated amount of retransmission.

Abstract: In one embodiment, a method for restructuring distorted capacitive touch data includes receiving an array of touch amplitude data associated with an electrode line of a capacitive touch sensor in response to a touch on a touch sensitive display. The method also includes detecting a distortion in the array of touch amplitude data and calculating, in response to detecting the distortion, a corrected array of touch amplitude data such that the corrected array of touch amplitude data represents the touch on the touch sensitive display.
