Latest Patents
Ahn holds a patent for a "Low-cost digital predistortion apparatus and method using envelope detection feedback." This invention presents a low-cost solution that includes a digital predistortion unit and an envelope detection feedback unit. The digital predistortion unit is responsible for converting the output of a predistorter into analog signals, frequency-modulating these signals into a pass band signal, and amplifying the frequency-modulated signal via a power amplifier. The envelope detection feedback unit plays a critical role by converting the difference between the input and output of the power amplifier into baseband signals, which are then transformed into digital signals. This process allows for the estimation of nonlinear distortion characteristics and the calculation of predistortion parameters to compensate for these distortions.
