Apparatus and method for receiving digital signal |
摘要 |
A receiving apparatus and method for a synchronizing process in the digital communication system is disclosed. A receiving apparatus includes: a A/D converting unit for performing an over-sampling process and outputting over-sampled points; a sample classifying unit for classifying the over-sampled points; a integration unit for integrating classified symbol values; a symbol synchronizing unit for selecting a point of symbol synchronization; a frequency estimating unit for estimating a frequency error; and a digital demodulating unit for demodulating values outputted from the symbol synchronizing unit and the frequency estimating unit to a signal. The present invention can simplify a configuration of the apparatus and reduce an amount of parameter-control. Moreover, the present invention can be used in a burst mode of a digital communication system.
