Abstract
Official abstract text for this publication.
An efficient baseband predistortion linearization method for reducing the spectral regrowth and compensating memory effects in wideband communication systems using effective multiplexing modulation technique such as wideband code division multiple access and orthogonal frequency division multiplexing is disclosed. The present invention is based on the method of piecewise pre-equalized lookup table based predistortion, which is a cascade of a lookup table predistortion and piecewise pre-equalizers.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of reducing adjacent channel power ratio in a multi-channel wideband communication system, the method comprising: generating a pre-distorted input signal by multiplying a baseband input signal and a polynomial predistortion coefficient from plurality of polynomial predistortion coefficients, wherein the polynomial predistortion coefficient is based on an absolute value of the input signal multiplied by the number of predistortion coefficients in the…
