Latest Patents

Ying Wu's latest patents include a "Round trip delay estimator and compensator for the echo canceller." This invention provides methods and systems for estimating and compensating for a round-trip or flat delay portion of an echo channel characteristic in an echo canceller. The method involves updating a filter coefficient vector of an adaptive filter that models the echo channel characteristic. An instant flat delay is estimated by analyzing the filter coefficient vector after each update, and periodic averages of the instant flat delay estimate are performed. A final flat delay estimate average is determined when the flat delay estimate average has converged. The length of the adaptive filter is adjusted in response to the final flat delay estimate average. Additionally, an improved echo canceller apparatus is provided, which includes an adaptive filter, a position detector, a periodic averager, and a level detector.

Another significant patent is related to "Distributed processing of high level protocols, in a network access server." This invention encompasses methods for distributing protocol processing among multiple computing platforms. It aims to enhance the cost/performance capabilities of communication equipment that supports serial links by distributing the protocol processing for higher-level protocols across various devices.
