Abstract: In order to reduce interference that may be generated when a plurality of signals having different subcarrier intervals are received, provided are a method of controlling a signal having a larger subcarrier interval to be suitable for a signal having a smaller subcarrier interval and a method of removing CFO interference. According to an embodiment of the present invention, the subcarrier intervals of a plurality of signals to be transmitted by wireless terminals are compared with each other, and signals are designed so that a signal having the largest subcarrier interval may be repeatedly transmitted. Therefore, interference that may be generated among different kinds of signals when the base station simultaneously receives the different kinds of signals to perform Fourier transform may be mitigated. In addition, interference caused by a CFO may be removed by previously compensating the CFO estimated in a time domain to perform Fourier transform.

Abstract: PURPOSE: A mesh node synchronization method in a wireless mesh system is provided to modulate a preamble of a neighbor node and broadcasting information. CONSTITUTION: An automatic gain controller transmits a network setup signal received from a neighbor node to a PHY(PHYsical Layer)(S531b). The PHY synchronizes time or frequency by using a preamble of the network setting signal(S532b). The PHY transmits the location information of a starting point of a super frame of the network setting signal to a DSP(Digital Signal Processor). The DSP synchronizes the clock of a mesh node through the location information.
