Latest Patents

Yu Hsien Chang holds a patent for an AI-assisted power amplifier optimization. This invention involves a compensator that addresses distortions in a power amplifier circuit. A power amplifier neural network (PAN) is trained to model the circuit using predetermined input and output signal pairs. Subsequently, a compensator is trained to pre-distort the signal received by the PAN. The compensator employs a neural network to optimize a loss between its input and the PAN output, utilizing a multi-objective loss function that incorporates both time-domain and frequency-domain loss functions. The trained compensator effectively performs signal compensation, resulting in a pre-distorted signal for the power amplifier circuit.
