Latest Patents
One of her latest patents is titled "Low complexity MIMO digital pre-distortion." This invention presents a method and a transmitter arrangement for cancelling cross talk and correcting power amplifier (PA) distortion in a MIMO configuration. The method involves combining an original baseband input signal with a crosstalk output signal generated from multiple MIMO branches. This innovative approach minimizes errors caused by crosstalk and PA distortion, enhancing the overall signal quality.
Another notable patent is "Linearization of intermodulation bands for concurrent dual-band power amplifiers." This patent discloses systems and methods for digital predistortion that compensates for both in-band and out-of-band intermodulation products. The concurrent multi-band transmitter includes a digital predistortion subsystem and an adaptation subsystem, which work together to process digital input signals and provide compensation for intermodulation distortion.
