    • PURPOSE: A multi-hop relay cooperative communication method for a wired communication system is provided to offer a new signaling method for using cooperative diversity capable of being obtained through a multi-hop relay. CONSTITUTION: A destination terminal is operated as a reception mode with a relay node of a first group while signal source terminal and relay node of a second group are operated in a transmission mode (S1510,S1520). The destination terminal restores a transmission signal from the signal source terminal using first reception signal and second reception signal (S1530). The first reception signal is generated when the destination terminal with a relay node of the first group is operated as a reception mode. The second reception signal is generated when the destination terminal with a relay node of the second group is operated as a reception mode. [Reference numerals] (AA) Start; (BB) End; (S1510) Even number relay nodes transmission mode of a signal source terminal, Odd number relay nodes reception mode of a destination terminal (Phase I); (S1520) Odd number relay nodes transmission mode of a signal source terminal, Even number relay nodes reception mode of a destination terminal (Phase II); (S1530) Restore transmission signals by MRC to phase I and phase II reception signals from the destination terminal
    • 目的:提供一种用于有线通信系统的多跳中继协作通信方法,为通过多跳中继获得的协作分集提供新的信令方法。 构成:目的地终端作为具有第一组的中继节点的接收模式操作,而第二组的信号源终端和中继节点在传输模式下操作(S1510,S1520)。 目的地终端使用第一接收信号和第二接收信号从信号源终端恢复发送信号(S1530)。 当具有第一组的中继节点的目的地终端被操作为接收模式时,产生第一接收信号。 当具有第二组的中继节点的目的地终端被操作作为接收模式时,产生第二接收信号。 (附图标记)(AA)开始; (BB)结束; (S1510)信号源终端的偶数中继节点传输模式,目的终端的奇数继电器节点接收模式(阶段I); (S1520)信号源终端的奇数继电器节点传输模式,目的地终端的偶数中继节点接收模式(阶段II); (S1530)将MRC的发送信号恢复到来自目的地终端的I相和II相接收信号
