With a total of 3 patents, his work has advanced the efficiency and effectiveness of audio processing in various applications.

Latest Patents

One of his latest patents is a "Method and apparatus for echo cancellation in an asymmetric communication system." This invention focuses on canceling echo signals that originate from a transmitter at a predetermined data rate. The system is designed to manipulate data rates of transmitted signals and reconstruct echo signals for the receiver's consideration. It intelligently reduces the computational complexity involved in the process, addressing the band-limited nature of echo signals.

Another significant patent is the "Acoustic echo cancellation equipped with howling suppressor and double-talk detector." This acoustic echo canceller (AEC) has been tested in real environments and integrates various digital signal processing methods for real-time implementation. The AEC can cover echo lengths of several hundred milliseconds and is based on a frequency domain implementation of the least-mean square (LMS) determination method. The invention includes two novel techniques: a howling suppressor to prevent oscillation and a double-talk detector to control the adaptation mechanism's step-size. The AEC program, developed in C-language, efficiently utilizes CPU resources, making it suitable for various platforms.
