Solid State Power Amplifier Linearization Using the Concept of Best Approximation in Hilbert Spaces

摘要：

Using the mathematical concept of best approximation in Hilbert spaces a predistorter structure is suggested to compensate both AM/AM and AM/PM conversion characteristics of a solid state power amplifier. To verify the effects of this linearization we generally consider it in a QAM signal transmission in an additive white Gaussian noise channel. The results are compared with the ideal linear case.
