摘要
A method of power amplifier predistortion that makes use of a compression detector circuit in a feedback loop in order to adapt the channel gain for changing transmitter behavior. By monitoring the compression behavior of the amplifier, the signal is scaled to compensate for gain and compression point variations in the power amplifier and transmitter, while keeping a predistortion correction function constant.
