Original Abstract Submitted
a method of digital memoryless pre-distortion includes receiving an input digital signal from a signal source, calculating a look-up table (lut) address from the input signal and a power scale, updating an lut value associated with the lut address based on the input signal and an output signal that is output from a power amplifier to a wireless communications channel, linearizing the output signal with the updated lut value, and outputting the output signal to the wireless communications channel. the steps of updating an lut value associated with the lut address and linearizing the output signal with the updated lut value are repeated until a level of linearization is achieved that meets a pre-defined standard.
