초록
A method of transmitting a signal according to the present invention includes: receiving a signal that is encoded with a predetermined code rate and that is modulated by a first modulation method from a base station; creating a signal that is obtained by demodulating the signal that is modulated by the first modulation method using a method corresponding to the first modulation method; creating a signal that is obtained by modulating the demodulated signal using a second modulation method while maintaining the predetermined code rate; and transmitting the signal that is modulated by the second modulation to a mobile station.Therefore, it is possible to reduce the cost of the relay station and simplify the system of the relay station. Further, during the modulation and demodulation, the symbol offset is changed to create various modulated and demodulated signals.
