Method of compensating for distortion in an amplifier |
摘要 |
A method of providing compensation for distortion imparted to an input signal, principally by an amplifier (18), compares a delayed version of the input signal (34) to the amplifier's output signal. The result of the comparison is an error signal that is fed back to minimize distortion. This feedback technique is applied to a transmitter (10) in combination with predistortion that is selected to compensate for at least some of the distortion provided by the transmitter's output amplifier (18). The remainder of the compensation is provided by the error signal which can be generated by a relatively low gain analog feedback loop.
