PROBLEM TO BE SOLVED: To sufficiently improve bit error rate of the signal received by an apparatus when the signal of such as MC-CDMA method is transmitted to the same apparatus through two communication paths.SOLUTION: A base station receiving section 31 receives the signal of MC-CDMA method from a base station. A transmission control section 33, based on the base station channel information and relay station channel information, determines a weight of each sub-carrier so that the channel condition, from a relay station 13 of each sub-band to a terminal, becomes identical with the channel condition, from a base station of the sub-band to a terminal. A transmission section 34, based on the weight of each sub-carrier, attaches a weight to the signal for a terminal of the sub-carrier. A transmission antenna 36 transmits the signal for the terminal attached with a weight to the terminal. The present invention can apply to a communication system of, for example, MC-CDMA method. |
