Systems and techniques relating to image cancellation in received
communications signals are described. In one aspect, a received
communications signal can include a desired signal and an image signal. A
leakage tracing signal can be generated, and the image signal can be
removed from the communications signal using the leakage tracing signal
mixed with the communications signal. Implementations can include
generating a first channel signal and a second channel signal, generating
a first filter using the first channel signal and the leakage tracing
signal, and generating a second filter using the second channel signal
and the leakage tracing signal. Removing the image signal from the
communications signal can include filtering the first channel signal
using the second filter to obtain a first filtered signal, filtering the
second channel signal using the first filter to obtain a second filtered
signal, and subtracting the second filtered signal from the first
filtered signal.
