Abstract
Linearization circuitry for predistortion of an input signal to an amplifier having a given distortion characteristic, including a correction circuit, which receives a stream of samples of the input signal at a high sample rate and which applies a correction to the samples responsive to the given distortion characteristic. The corrected samples are preferably low-pass filtered. A decimation circuit receives the corrected samples from the correction circuit and reduces the sample rate of the stream for output to the amplifier, to a reduced rate substantially less than the high sample rate. The present invention enables significant parts of the circuitry to operate at much lower sample rates that previously achievable and lends itself naturally to parallel implementations.
