Method of cooperative multihop relay communication for wired communication system

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
