摘要：
The use of High Power Amplifiers (HPA) in digital communications is plagued with non-linear (AM/AM and AM/PM) distortion. This is specially acute for those modulations that are not constant amplitude, such as OFDM or MQAM We present a pre-distortion algorithm that, in contrast to previously researched architectures, is unconditionally convergent.
