Latest Patents

Donghan Kim holds a patent for a "Low complexity direct-to-LUT digital pre-distortion method." This invention involves a distortion apparatus for a power amplifier that includes pre-distortion circuitry with a memory polynomial look-up-table (LUT) circuit. The post-distortion circuitry updates the pre-distortion circuitry based on the output of the power amplifier. The pre-distortion circuitry consists of multiple LUTs, each corresponding to different memory depths of a memory polynomial from a Volterra series. The output of the memory polynomial LUT circuit is a summation of outputs from each LUT, multiplied by the input sample delayed according to the respective memory depth.
