    Abstract: PURPOSE: A synchronization device in a wireless network system and a method thereof are provided to set a distribution synchronization mode by considering an electron delay and mobility depending on a distance between nodes. CONSTITUTION: A node performs a ranging procedure with neighbor nodes(S602). The node estimates a propagation delay value depending on a distance the neighbor nodes through the ranging procedure(S604). When a difference between a maximum propagation delay value and a minimum propagation delay value of the propagation delay value is greater than a CP(Cyclic Prefix) section(Tcp), the node requests to change signal transmission timing to the neighbor node having the maximum propagation delay value or the neighbor node having the minimum propagation delay value(S606,S608). [Reference numerals] (AA) Yes; (BB) No; (S602) Ranging procedure; (S604) Estimating a propagation delay relative to neighboring nodes; (S607) Setting an FFT starting point; (S608) Requesting change of transmission timing; (S610) Change is accepted?; (S612) Measuring interference; (S614) Interference amount > reference value; (S618) Requesting forcible change of a clock value; (S620) Setting the FFT starting point as the minimum propagation delay value

CONSTITUTION: A super-frame(SU,100) is the largest unit frame used for a wireless mesh network. Nodes within an OFDMA based wireless mesh network implement communication using the super-frame for data transmission and dispersed connection control. The super-frame comprises one or more frames, one of which is a network control frame(NCF) used by the nodes and the others of which are scheduling and data frames(SDF). The frame is composed of one or more subframes(SF).

    Abstract: PURPOSE: A signal transmitting method and a signal receiving method are provided to estimate the channel of a cell to which a terminal belongs and the channel of a signal coming from a neighbor cell, thereby reducing the interference of the neighbor cell. CONSTITUTION: In order to be orthogonal to the pilot pattern of a first user terminal, a second user terminal changes its own pilot pattern(S522). A center BS(Base Station) receives a transmitting signal from the first user terminal in a nth frame(S524). The center BS estimates a channel with the first and second terminals(S528). A neighboring BS detects the transmitting signal of the second user terminal with a channel estimation value(S530). The center BS eliminates an interferential signal with the channel estimation value and transmitting signal of the second user terminal(S536).
