Latest Patents

One of Wu's latest patents is focused on low complexity no delay reconstruction of missing packets for LPC decoders. This invention addresses the issue of lost frame reconstruction by analyzing previous good or reconstructed frames to determine a category for the lost frame. A percentage is associated with the determined category, allowing for the zeroing out of a top percentage of magnitude samples in the excitation of the previous frame to produce a reconstruction excitation. This innovative approach enhances the quality of reconstructed frames in communication systems.

Another notable patent is the 4X crystal frequency multiplier with an operational amplifier buffer between 2X multiplier stages. This frequency-multiplying circuit generates a multiple of the fundamental frequency of a crystal oscillator. The design includes a first differential multiplier that generates a frequency-doubled output, which is then buffered and compared to a reference to produce differential buffered signals. These signals are applied to a second differential multiplier to achieve a final quadrupled-frequency output, showcasing Wu's expertise in electronic circuit design.
