Patent ID: 8891715

Claim:
A predistortion system to generate a predistortion signal, comprising: a second order harmonic correction section including a first set of mixers to generate a second harmonic correction signal based on real and imaginary parts of a data signal and to generate at least one intermediate signal for the second harmonic correction signal generation, wherein a difference of the squares of the real and imaginary parts of the data signal to be generated using at least one mixer of the first set of mixers, and wherein another two mixers of the first set of mixers having inputs for a first set correction coefficients; a third order harmonic correction section including a second set of mixers to generate a third harmonic correction signal based on the real and imaginary parts of the data signal and the at least one intermediate signal including at least a component of the difference of the squares of the real and imaginary parts of the data signal, wherein two mixers of the second set of mixers having inputs for a second set of correction coefficients; an image correction section to generate an image correction signal; and an output for the predistortion signal, wherein the predistortion signal is a combination of the second harmonic correction signal, third harmonic correction signal, and the image correction signal.
