Abstract

We have designed a linear power amplifier for a VHF frequency‐hopping (FH) transmitter using an adaptive predistortion linearizer. We employed an analog polynomial linearizer as a predistorter. In the predistortion linearizer, the recursive least squares (RLS) algorithm is employed for the optimization process to minimize the errors between the predistorter and postdistorter output signals. The experimental results of the FH transmitter demonstrate that the spectral spreading is reduced by 10 dB. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 31: 457–460, 2001.

## Abstract This paper presents the new architecture of an adaptive predistortion linearizer. In the proposed linearizer, most of the processes, including the predistortion, are performed with a digital signal processor (DSP).

Obtaining unknown NMR parameters from experimental spectra of exchanging systems is, from a mathematical point of view, associated with the solution of an inverse problem. Inverse problems are usually solved by iterative procedures and calculations may not always converge and the solutions are rarel
