    • 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).
    • 目的:提供信号发送方法和信号接收方法,以估计终端所属的小区的信道和来自相邻小区的信号的信道,从而减少相邻小区的干扰。 构成:为了与第一用户终端的导频模式正交,第二用户终端改变其自己的导频模式(S522)。 中心BS(基站)在第n帧从第一用户终端接收发送信号(S524)。 中心BS估计具有第一和第二终端的信道(S528)。 相邻BS使用信道估计值来检测第二用户终端的发送信号(S530)。 中心BS消除了具有第二用户终端的信道估计值和发送信号的干扰信号(S536)。

    • PURPOSE: A device for constructing a mobile communication channel is provided to differently construct a pilot channel and a communication channel for a high communication channel and a low communication channel. CONSTITUTION: At least one modulator for a high communication(25a-25n) modulates high speed signals used for private pilot channels. At least one modulator for a low communication(23a-23n) modulates low speed signals used for common pilot channels. A modulator for the common pilot channels(21) modulates the signals of the common pilot channels. A synthesizer(27) synthesizes the signals received from the at least one modulator for a high communication(25a-25n), the at least one modulator for a low communication(23a-23n) and the modulator for the common pilot channels(21), and outputs the synthesized signals. A high frequency power amplifier(29) performs a power amplification for the received signals from the synthesizer(27). An antenna(31) receives the signals from the high frequency power amplifier(29), and emits the received signal.
