Latest Patents

Kao's most recent patents include two notable inventions that streamline frequency offset estimation and timing synchronization processes in wireless communication systems.

1. **Method and Circuit for Frequency Offset Estimation in Frequency Domain in the Orthogonal Frequency Division Multiplexing Baseband Receiver for IEEE 802.11a/g Wireless LAN Standard** - This patent outlines a method that begins by calculating the phase angle of a signal field from the input signal, which has undergone Fast Fourier Transformation (FFT) and channel equalization. The frequency offset error, originating from at least one frequency offset estimation process in the time domain, is then estimated based on this phase angle.

2. **Method and Circuit for Fine Timing Synchronization in the Orthogonal Frequency Division Multiplexing Baseband Receiver for IEEE 802.11a/g Wireless LAN Standard** - This invention presents a method for fine timing synchronization. It involves detecting the end point of a short preamble, delivering samples to a matched filter, and generating multiple correlation peaks. The method then includes searching for the first maximal peak point with the highest intensity and estimating the start point of the second long training sequence (LTS) based on identified time indexes.
