Processing a transponder signal received from a transponder may include providing a first signal that is in-phase with the transponder signal and a second that is off-phase with the first signal. A first transformed signal is generated using the first signal, where the first transformed signal has a first characteristic equal to the first characteristic of the first signal and a second characteristic different from the second characteristic of the first signal. A second transformed signal is generated using the second signal, where the second transformed signal has a first characteristic equal to the first characteristic of the second signal and a second characteristic different from the second characteristic of the second signal. Information incorporated in the transponder signal is obtained using a combination of the first transformed signal and the second transformed signal. |
