Apparatus and method for extracting synchronization in a communication system

The present invention by utilizing a preamble signal of a structure which is periodically repeated discloses a sync extraction apparatus and method for performing synchronization acquisition frame. The present invention by providing a receiving apparatus and a method which comprises obtaining the input signal and without obtaining a simple correlation value between the delay signal the signal and a correlation value is combined after obtaining the sum of first obtaining a frame sync, frame sync extraction circuit reduce the complexity of the implementation, there is an effect that can increase battery cycle of the device reduces power consumption Go adder
