Latest Patents

Dongfang Ning's latest patents include a method, device, and system for signal distortion pre-correction. This invention discloses a device that comprises a signal distortion correction network module, a correction parameter trainer, a data collection module connected to an external power amplifier module, and a first conversion module. The data collection module is designed to perform time-division collection on output signals from the power amplifier module and output analog feedback signals to the first conversion module. The first conversion module then converts these analog feedback signals into digital feedback signals. The correction parameter trainer determines a correction parameter based on the digital feedback signals and a forward signal inputted. The signal distortion correction network module corrects the forward signal based on this correction parameter, ultimately outputting a pre-corrected signal.

Another notable patent involves a signal distortion pre-correction method, device, and non-volatile storage medium. This application relates to the field of communications and provides a method for obtaining mutual coupling filtering parameters and a predistortion coefficient candidate set through training feedback signals collected by a multi-channel coupling element. This allows for mutual coupling filtering processing on the forward signal of the digital channel, ensuring that the selected predistortion coefficient considers the mutual coupling factor of the digital channel.
