Title: Qian C Xie: Innovator in Modem Technology
Introduction
Qian C Xie is a notable inventor based in Long Branch, NJ (US), recognized for his contributions to modem technology. He holds 2 patents that focus on enhancing the performance of modem receivers. His work has significantly impacted the field of telecommunications.
Latest Patents
One of Qian C Xie's latest patents is titled "Re-configurable decoding in modem receivers." This invention provides methods and systems for operating a modem receiver, such as an ADSL modem receiver. As incoming data signals are received, a decoding scheme is selected from a plurality of decoding schemes based on a predetermined downstream data rate. In this approach, a soft receiver architecture of an ADSL modem can select between relatively complex and simple decoding schemes based on the signal-to-noise ratio (SNR).
Another significant patent is focused on "Techniques to cancel echo tail." This invention provides techniques for reducing the magnitude of echo tails in a near-end modem. The echo tail canceller generates a signal that cancels the echo tail. One characteristic of the echo tail canceller is determined during a time when only the near-end modem is scheduled to transmit signals. Another characteristic may be determined when a body echo canceller has reached convergence and can be re-determined periodically thereafter. The near-end modem subtracts the echo tail canceller signal from any received signal to effectively cancel the echo tail.
