Latest Patents
One of his latest patents is titled "Systems and methods for equalization in radio frequency signal paths." This invention involves a wireless communications device that includes a transmit signal path with a digital-to-analog converter and associated circuitry. It also features a receive signal path with an analog-to-digital converter and a magnitude detector. The signal controller in this device determines amplitude and phase distortion based on the magnitude detector's output, generating an equalization filter to pre-distort regular traffic output through the transmit signal path. This approach effectively compensates for both amplitude and phase distortions in RF signal paths.
Another significant patent by Alexander X Pei is "Electronic device with a distortion correction circuit for a power amplifier, and associated methods." This electronic device comprises a radio frequency modulator, a power amplifier, and a distortion correction circuit. The distortion correction circuit includes a variable gain amplifier and an amplitude correction control loop, which utilizes logarithmic converters to control the gain of the variable gain amplifier. This innovation aims to correct distortion in the output signal from the power amplifier, enhancing the overall performance of the device.
