Apparatus and method for synchronizing using auto-correlation character

1. the art that the invention defined in the claims The present invention will on the synchronization device and a method using a relative difference between the maximum correlation value and a correlation value around. 2. The invention attempts to solve the technical challenges The present invention synchronization for acquiring synchronization by using a cross-correlation properties of a similar noise signal determines the synchronization position by using a relative difference between the maximum correlation value and around a correlation value with the maximum nature of the correlation value was used in the synchronization device intended to provide a device and method. 3. Resolution of the subject matter of the invention, The present invention, matching the wake means for obtaining a correlation value between the received signal and the synchronization signal; Envelope detection means for detecting a size (Magnitude), remove the influence of the phase (Phase) on the correlation value output from the matched Filter means in order to reduce the influence of the frequency offset; Slot accumulation means for accumulating the correlation value from the envelope detection means at a slot unit; And by determining the synchronization position by using a relative difference between the maximum correlation value and a correlation value close to include synchronization means for acquiring synchronization. 4. An important use of the invention, The invention yiyongdoem asynchronous communication system or the like.
