With a total of three patents to his name, Wang's work has had a considerable impact on audio and video conferencing technologies.
Latest Patents
Wang's latest patents include innovative systems and methods for generating long-term signal level estimates during automatic gain control. One of his patents focuses on a method where a computing device receives an input signal derived from an upstream input signal. The device selects a subset of the feed data, divides it into analysis intervals, and calculates statistical averages to generate a Gaussian distribution. This distribution helps in determining the long-term signal level estimate, which is then used to apply a first stage gain to the input signal.
Another significant patent by Wang involves a two-stage digital automatic gain control system. This system is designed for audio and video conferencing applications to maintain a stable audio level. The first stage applies a gain based on a long-term estimate of the signal level, while the second stage assists in achieving the target level using a short-term estimate. This dual approach enhances the accuracy and reliability of audio levels during conferencing.
