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.
