Embodiments of methods receiving circuits and apparatuses compensate for an IQ mismatch using a test signal positioned in a guard band. One embodiment of a method can include converting a sum of a received signal and a test signal positioned in a guard band to a first signal and a second signal of an intermediate frequency or a base band using an IQ mixer, detecting the IQ mismatch using the test signal respectively included in subsequent signals corresponding to the first signal and the second signal and compensating for the detected IQ mismatch using the IQ mismatch.
