摘要： An apparatus for linearizing the output of a wideband amplifier by digitally predistorting the input to the amplifier in a way that just compensates for the distortion in the amplified signal, comprising a pipeline controller (12), for providing pipeline controller signals, and a pipelined predistorter (11), consisting of several stations, serially connected to each other, wherein each station performs one or more tasks concurrently, under the direction of the pipeline controller (12). The result is a digital predistorter with a bandwidth large enough to linearize, by itself, the entire output of a wideband amplifier. More generally, an apparatus for linearizing a wideband amplifier by using digital signal processing performed using a pipeline architecture, as opposed to using a sequential processing architecture, under the supervision of a pipeline controller.
