Abstract

A code synchronization apparatus in a multi-carrier direct sequence spread spectrum communication system and method thereof are disclosed. The purpose of the present invention is to solve the problems that when using the conventional code synchronization apparatus used in a single carrier system, the time necessary for synchronization as well as the complexity of the system are increased. To do this, the present invention discloses a code synchronization apparatus in a multi-carrier direct sequence spread spectrum communication system and method thereof which are capable of obtaining a stabilized code synchronization, using a code synchronization method suitable to the situation to adjust the symbol combining gain and the symbol integration period adaptively to the channel situation.
