Abstract
According to the present invention, a transmitter includes a first transmitting antenna and a second transmitting antenna, and each of the first transmitting antenna and the second transmitting antenna transmits a signal through at least one or more odd subcarriers and at least one or more even subcarriers. In the mobile communication system, the first transmission antenna and the second transmission antenna are encoded by using a transmission diversity scheme in which a first symbol and a second symbol to be used for initial channel estimation of the receiver are preset during a preset period set by the transmitter. Transmit to the receiver on each of the odd subcarriers and the even subcarriers, respectively, the receiver receives a signal during the set interval, the channel frequency responses of the odd subcarriers of the first transmitting antenna and the second Simple linear operation of channel frequency responses of even subcarriers of a transmitting antenna The channel of the even subcarriers of the first transmitting antenna using the estimated channel frequency responses of the odd subcarriers of the first transmitting antenna and the channel frequency responses of the even subcarriers of the second transmitting antenna. By estimating frequency responses and channel frequency responses of odd subcarriers of the second transmitting antenna, channel estimation may be adaptively performed in a channel environment.
