    Abstract: PURPOSE: A frame synchronization acquisition circuit by using the minimum value of inter correlation value of a precode and a method for acquiring the synchronization by using the circuit are provided to overcome the effect of noise by using the characteristics of precode with utilizing only one buffer. CONSTITUTION: A frame synchronization acquisition circuit by using the minimum value of inter correlation value of a precode includes a block(10) for measuring a minimum value, a block(20) for determining minimum value and maintaining it, and an initialization block(30). The block(10) measures the minimum value by comparing the data inputted thereto with the stored value. The block(20) outputs the frame synchronization time by determining and maintaining the minimum value with receiving the information transmitted from the block(10). And, the initialization block(30) initializes the coefficient values of the block(20).
