Title: Innovations of Chinghsiu Shih in Receiver Calibration
Introduction
Chinghsiu Shih is an accomplished inventor based in Irvine, CA. He has made significant contributions to the field of receiver calibration, particularly through his innovative patent that addresses gain mismatch and quadrature phase errors.
Latest Patents
Chinghsiu Shih holds a patent titled "Systems and methods for coherent adaptive calibration in a receiver." This patent describes an improved calibration system designed to calibrate the I and Q paths of a receiver. The system corrects for gain mismatch and quadrature phase errors by using a calibration signal and a reference signal that are coherently generated from the same single frequency source. The calibration signal is input into the receiver and propagated along the I and Q paths simultaneously with a received signal. The reference signal extracts the calibration signal from the I and Q paths, allowing for the measurement of phase and gain errors. The system adaptively calibrates these errors by iteratively measuring and reducing them to the desired level or eliminating them altogether. Chinghsiu Shih has 1 patent to his name.
