His work has had a profound impact on the efficiency and effectiveness of communication technologies.
Latest Patents
One of his latest patents is titled "Receiver-side selection of DSL communications mode." This invention describes a client premises digital subscriber line (DSL) modem with multi-mode capability. During initialization, the modem estimates whether channel conditions favor processing data according to a lower data rate DSL standard, such as ADSL2, over a higher data rate standard like ADSL2+. If the conditions are favorable, the modem configures itself to operate at the lower data rate, optimizing the effective data rate. The transmitting modem can continue to operate at the higher data rate, allowing for efficient data processing.
Another significant patent is "Methods and apparatus for crystal oscillator drift estimation and compensation." This method involves receiving bursts of data that are subject to long-term and short-term frequency drift. The invention determines the intercept of the long-term drift and compensates for it in subsequent bursts. Additionally, it calculates the slope of the short-term drift to ensure accurate compensation, enhancing the reliability of data transmission.
