Latest Patents

Jin-Sub Moon holds a patent for an "Apparatus and method for compensating error for analog quadrature modulator (AQM)." This invention provides a comprehensive solution for compensating errors in AQM systems. The apparatus and method involve measuring and compensating errors using returned I/Q digital signals. The process includes detecting a DC offset signal by averaging sampling values of returned I/Q digital signals. It also involves detecting a gain compensating signal using the maximum value in a period of the I/Q digital signals, which have had the DC offset compensated. Additionally, the invention detects a phase compensating value of the I/Q digital signals based on the sum of absolute values for differences between the gain compensated I-digital signals and Q-digital signals. This sequentially removes phase error, gain error, and DC offset from the inputted digital signal to effectively compensate the AQM error.
