Seung-Kwon Back has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7233635
    Abstract: A symbol synchronization apparatus and method for synchronizing symbol digitally is disclosed. In the present invention, digital symbols are generated by an A/D converting unit. Based on digital symbols, a symbol timing value is calculated. The symbol timing value is used for determining a best symbol timing. According to the best symbol timing, a clock phase is determined and A/D converting unit uses newly determined clock for generating digital symbols. As a result, the present invention can perform an over-sampling process in higher resolution than a sampling frequency by using only one A/D converter. Therefore, the present invention may increase economic efficient and reduce complexity of hardware.
