Abstract
Disclosed is a symbol synchronization method in an OFDM-based communication system which includes multiple access nodes supporting wireless connection of terminals, supports multi-connection of each terminal for the access nodes and performs synchronization by means of a cyclic prefix. The symbol synchronization method includes monitoring connection of a new access node; setting a number of times by which the new access node transmits equal symbols and a number of times by which at least one existing access node transmits the equal symbols when the connection of the new access node is detected; transmitting the equal symbols by the determined number of times by each access node; and performing synchronization by means of the symbols received from the access nodes by the terminal.
