Latest Patents

One of his latest patents is the "Wireless access point apparatus and channel switching method thereof." This invention includes a mixer, an analog low-pass filter (ALPF), an analog-to-digital converter (ADC), a radar detector, and a controller. The mixer is designed to mix a wireless signal with a carrier signal for frequency conversion. The ALPF filters the wireless signal to eliminate components outside its passband. The ADC converts the wireless signal from analog to digital form. The radar detector identifies whether the wireless signal contains any radar signals, while the controller adjusts the carrier frequency based on the radar detector's findings to switch between different channel types.

Another significant patent is the "Signal receiving apparatus and operation method thereof having phase compensation mechanism." This invention features a receiving circuit with two paths that perform frequency down-conversion and analog-to-digital conversion on an input signal. The circuit uses a RF training signal for phase compensation and a data signal from an antenna for beamforming. A phase difference calculation circuit performs cross-correlation on the receiving signals to generate a compensation signal, ensuring that both signals have identical phases after compensation.
