Title: Innovations of Xihao Li in Phase and Frequency Error Processing

Introduction

Xihao Li is a notable inventor based in Ottawa, Canada, recognized for his contributions to the field of communications technology. He holds two patents that showcase his expertise in phase and frequency error processing, which are critical for enhancing communication systems.

Latest Patents

One of Xihao Li's latest patents is focused on phase and frequency error processing. This invention includes an apparatus with a phase path and a frequency path. The phase path is designed to process phase errors in communications between network nodes and features a closed-loop feedback loop controller. The frequency path, which operates independently, processes frequency errors in the same communications. The method outlined in this patent involves selecting packets for phase and frequency processing separately, ensuring efficient error management.

Another significant patent by Xihao Li is a clock recovery device with a state machine controller. This device is engineered to recover frequency and timing information from incoming packet streams over asynchronous packet networks. It incorporates a phase locked loop (PLL) block with predefined states, including a type II PLL operation. The state machine controller manages transitions between these states based on changes in the incoming packet stream, while a controlled oscillator generates an output signal in response to the PLL block.
