Latest Patents

One of his latest patents is a method and apparatus for reducing noise pumping due to noise suppression and echo control interaction. This innovative approach processes an input signal through noise suppression (NS) and echo control (EC) using a multipath model. The design effectively reduces noise pumping effects while maintaining the performance of echo control. A copy of a 'noisy' input signal is sent to an EC component before it reaches the NS component. This allows the NS component to process the signal first when there is a consistent noise level for estimation. The EC component then analyzes the noisy signal as if it were the first component in the signal chain, determining the necessary actions to take. These actions are subsequently applied to the clean signal received from the NS component.
