Abstract:
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.

Claim (Index 2):
A method comprising:\n providing a pre-distortion lookup table (LUT) having N first entries, N being an integer equal to or greater than unity; providing a pre-equalization lookup table (LUT) having M second entries, M being an integer equal to or greater than unity, the pre-equalization LUT being associated with a pre-equalizer; determining an index based on a magnitude of a baseband input signal; generating a sample by multiplying the baseband input signal with an entry of the N first entries in accordance with the index; and pre-equalizing the sample using an entry of the M second entries in accordance with the index to generate a pre-equalized signal.
