Title: Haixiang Liang: Innovator in Digital Signal Processing
Introduction
Haixiang Liang is a prominent inventor based in Atherton, California. He has made significant contributions to the field of digital signal processing, holding a total of 10 patents. His work focuses on enhancing the efficiency and performance of communication networks.
Latest Patents
One of his latest patents addresses reduced power consumption for digital signal processing (DSP)-based reception in time-division multiplexing (TDM) passive optical networks (PONs). This invention includes an optical network unit (ONU) that features a receiver designed to receive a continuous-mode TDMA downstream signal from an optical line terminal (OLT). The ONU also comprises a photodetector (PD) that converts the downstream signal into an electrical or RF signal, followed by an analog-to-digital converter (ADC) that transforms the signal into a digital format. Additionally, a burst-mode data recovery stage is included to synchronize and recover data from the digital signal.
Another notable patent involves crosstalk channel estimation for legacy consumer premises equipment (CPE). This invention pertains to a digital subscriber line (DSL) network device that connects to DSL communication lines. The device features multiplexing circuitry that transmits signals to both vector-compliant and legacy CPE. The processing circuitry initiates the transmission of orthogonal pilot sequences and data symbols, while also pre-processing line errors to mitigate far-end crosstalk.
