Latest Patents

Zhao's latest patents include a reconfigurable transmitter and receiver, along with methods for reconfiguring them. This invention discloses a system that utilizes an adaptive control circuit to generate control signals based on frequency band information of an input signal. The system clock circuit generates a system clock, while a preprocessing circuit processes the received baseband signal to produce a frequency band signal. Additionally, a digital intermediate frequency processing circuit processes this signal to generate a digital intermediate frequency signal, which is then converted into an analog signal by a digital-to-analog conversion circuit. Finally, an analog transmitting circuit transmits the analog signal.

Another notable patent is the predistortion processing apparatus and method. This invention features an auxiliary feedback module that extracts a nonlinear distortion signal from an analog signal. The feedback signal is input into an auxiliary model coefficient training module, which trains an auxiliary coefficient based on the feedback and predistortion signals. The system also includes a radio frequency signal feedback module and a predistortion model coefficient training module, which work together to perform predistortion processing on an input intermediate frequency signal.
