Abstract
A mobile communication system a transmitter includes a first transmission antenna and a second transmission antenna and the first and second transmission antennas transmit signals through at least one odd carrier and at least one even carrier. The transmitter determines a first symbol and a second symbol to be used for initial channel estimation of a receiver encodes the first symbol and the second symbol by a preset transmit diversity scheme for a preset time and transmits the encoded first and second symbols to the receiver through odd carriers and even carriers of the first transmission antenna and the second transmission antenna. The receiver receives a signal for the preset period estimates channel frequency responses of odd carriers of the first transmission antenna and channel frequency responses of even carriers of the second transmission antenna and estimates channel frequency responses of even carriers of the first transmission antenna and channel frequency responses of odd carriers of the second transmission antenna by using the estimated channel frequency responses.
