Latest Patents

One of Liu's latest patents is titled "Device and method for downlink gain compensation as well as radio unit comprising the device." This invention discloses a device designed for downlink gain compensation at a radio unit. The device includes a pre-distortion circuit, a digital gain adjuster, a gain determiner, and a first gain controller. The pre-distortion circuit generates and applies a pre-distortion to an input signal. The digital gain adjuster applies an adjustable gain to the output signal from the pre-distortion circuit. The gain determiner calculates the gain difference between a target downlink gain and the current downlink gain. Finally, the first gain controller manages the digital gain adjuster based on this gain difference. A radio unit that incorporates this device is also part of the patent.
