Latest Patents

One of his latest patents is a digital demodulation circuit using an automatic gain control circuit with a temperature compensation function. This circuit amplifies a received signal of an intermediate frequency with a variable gain control amplifier, converting it into a baseband signal. The design separates the signal into a common-mode component and an orthogonal component, generating a first gain control voltage based on these components. Additionally, a temperature correction value is produced by smoothing a pulse-width modulation signal that corresponds to ambient temperature. This value is added to the first gain control voltage to create a second gain control voltage, allowing the variable gain control amplifier to effectively amplify the received signal. This innovation achieves both temperature compensation and automatic gain control in a simplified circuit configuration.

Another notable patent is the cross-polarization interference compensation apparatus and method. In this invention, a first signal with a first polarization direction and a second signal with a second polarization direction are received. The phase of the second signal is controlled using a phase control signal, and an interference compensation signal is generated through a weighted combination of the controlled signal. The weighting coefficients are set to ensure that the interference compensation signal aligns with the cross-polarization interference component of the first signal. By estimating the phase difference between the two signals, the phase control signal is adjusted to synchronize their phases, effectively compensating the first signal for any cross-polarization interference caused by the second signal.
