  • Predistortion system and method using a pilot signal
    Patent number: 6496062
    Abstract: A predistortion system uses a pilot signal to determine a predistortion function which is used to produce amplitude and/or phase adjustment(s) of an input signal on a signal path. Rather than simply detecting the input signal envelope before and after distortion generating circuitry, such as an amplifier, a pilot signal is provided on the signal path prior to the distortion generating circuitry. After the distortion generating circuitry, the pilot signal is detected. The predistortion system can determine the predistortion function by using the generated pilot signal and the detected pilot signal, for example, to provide improved characterization of the amplifier amplitude and/or phase response or to directly improve the determination of the predistortion function.
