Document Type and Number:
Japanese Patent JP2002506306
Kind Code:
A
Abstract:
A feed forward arrangement for linearizing a distorting element such as an amplifier. The arrangement has error correction means which produces an error correction signal that is combined with the output signal of the distorting element to produce a corrected output signal. A pilot signal is injected into the distorting element path so as to be processed by the error correction means and the presence of the pilot signal in the corrected output signal is monitored by comparison with the pilot signal so as to produce another error correction signal to adjust the error correction means. The pilot signal is advantageously derived from the distorting element input signal.
