    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).
