Title: Tae Ryun Chang: Innovator in Wireless Communications
Introduction
Tae Ryun Chang is a prominent inventor based in Santa Clara, CA, known for his significant contributions to wireless communications. With a total of 11 patents to his name, he has made remarkable advancements in the field, particularly in channel estimation and decoding techniques.
Latest Patents
One of his latest patents is titled "Methods and systems for effective channel estimation in OFDM systems." This invention provides a method and apparatus for channel estimation in wireless communications. After performing an initial channel estimation and estimating the effective channel length (ECL), a weighting based on the ECL is applied to reduce noise from the initial estimate, thereby enhancing accuracy. The invention allows for different weightings to be applied for varying channel lengths, and a threshold can be used during the ECL estimation to adapt to different channel environments.
Another notable patent is "Methods and systems for modified maximum-likelihood based TBCC decoding." This invention discloses a method and apparatus for decoding tailbiting convolutional codes (TBCC). The proposed modified maximum-likelihood TBCC decoding technique maintains the error correction performance of optimal maximum-likelihood decoding while significantly reducing computational complexity. Compared to other sub-optimal TBCC decoding algorithms, this technique achieves improved packet error rate performance with similar computational demands.
