Claim:
1. A data transmission method of a source node, comprising: transmitting data to a relay node in a first time slot; transmitting the data to a destination node in a second time slot after the first time slot; wherein the relay node transmits the data to the destination node in the second time slot, based on FD (Full Duplex) or HD (Half Duplex), wherein the data includes first symbols and second symbols, wherein the first symbols are derived by applying a complex conjugation to the second symbols, or the second symbols are derived by applying a complex conjugation to the first symbols, wherein the first symbols and the second symbols are allocated in other frequency resource, at a same time slot, and wherein the source node modulates the data using QPSK or 16 QAM, and transmits the modulated data to the relay node in the first time slot.
