Abstract
The present invention is an improved linearizer that implements more complex transfer functions to provide the necessary linearization performance with a reasonable amount of signal processing resources. Particularly, the linearizer operates on an analog-to-digital converter and comprises a distortion compensator and one or more factored Volterra compensators, which may include a second-order factored Volterra compensator, a third-order factored Volterra compensator, and additional higher-order factored Volterra compensators. Inclusion of factored Volterra distortion compensators improves linearization processing performance while significantly reducing the computational complexity compared to a traditional Volterra-based compensator.
