Abstract
One exemplary embodiment is directed to an efficient baseband predistortion linearization method. The exemplary method at least reduces the spectral regrowth and compensates for memory effects in wideband communication systems. The exemplary method uses an effective multiplexing modulation technique, such as wideband code division multiple access and orthogonal frequency division multiplexing. Another exemplary aspect utilizes a piecewise pre-equalized lookup table based predistortion, which is a cascade of a lookup table predistortion and piecewise pre-equalizers.
