Title: Lihe Liu: Innovator in Digital Subscriber Line Technology
Introduction
Lihe Liu is a prominent inventor based in Shenzhen, China. He has made significant contributions to the field of digital subscriber line (DSL) technology. With a total of 4 patents, Liu's work focuses on enhancing the performance and management of DSL systems.
Latest Patents
One of Liu's latest patents is titled "Configuring virtual noise parameters of very high-speed digital subscriber line." This invention involves an apparatus that transmits a DSL signal from multiple subscriber lines based on a reference virtual noise power spectral density (PSD). The reference virtual noise PSD is derived from an upper bound for the worst-case far-end crosstalk (FEXT) PSD in the subscriber lines. Additionally, the apparatus includes a processor that implements a method for obtaining the upper bound for the worst-case FEXT PSD and determining bit-loading for the lines based on the referred virtual noise.
Another notable patent is the "Method, device and system for managing lines." This invention provides a method for collecting showtime parameters of user lines and calculating crosstalk information based on these parameters. The method simplifies and accelerates the dynamic spectrum management (DSM) algorithm, allowing for more direct and accurate grouping of user lines.
