With a total of 2 patents to his name, Cai Li continues to push the boundaries of innovation in his field.

Latest Patents

Cai Li's latest patents include a "Transmitting System and Receiving System, and Transmitting Method and Receiving Method." This invention describes a system capable of implementing communications with multiple rates. The transmitting system features a transmitting-side selection apparatus that selectively inputs bit data to either a first or second constellation mapping modulation apparatus based on the transmission rate. The first constellation mapping modulation apparatus performs modulation on the input signal to obtain a constellation-mapped signal, while the second apparatus does the same for its respective input. Additionally, an OFDM modulation apparatus is employed to modulate the constellation-mapped signal for transmission.

Another notable patent is the "Bias Voltage Control System and Bias Voltage Control Method." This invention focuses on an optical IQ modulator that includes an I-branch Mach-Zehnder Modulator (MZM) and a Q-branch MZM, each receiving specific bias voltages. The system incorporates a photo-detector that converts part of the optical signal output into an electrical signal, which is then processed by an analog-to-digital converter. A digital signal processor superimposes dither signals on the bias voltages to generate harmonic signals, controlling the voltages based on the DC component and harmonic signal powers.
