US 2003/0156671 A1 · Apparatus and method for digital symbol synchronization

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.
