    • A system and a method for transmitting and receiving signals in a relay communication system are provided to use radio resources and to cancel signal interference effectively. A base station receives the first signal from at least one mobile station, which exists at the common range between the base station and a relay station, at the first time domain. The base station decodes the first signal. At the second time domain, the base station receives the second signal the relay station relays. The base station removes the first signal component from the second signal and obtains the third signal. In this case, the relay station receives the first signal as an interference signal at the first time domain, and the second signal contains the first signal component and the third signal component the relay station receives from a mobile station which is out of the range of the base station.

    • An apparatus and a method for obtaining channel state information in wireless relay networks are provided to reduce feedback signals and minimize a waste of resources, in the case of using a fixed RS(Relay Station), and to transmit signals adaptively according to channel conditions by using the channel information between a source, an RS, and a BS(Base Station). A BS, if uplink signals are received from an RS and an MS(Mobile Station), estimates the channels of SD(Source-to-Destination) and SR(Source-to-Relay station) links using the pilot signals contained in the received uplink signals(311,313). Also the RS receives an uplink signal from the MS and estimates the channel of an RD(Relay station-to-Destination) link using the pilot signal contained in the received uplink signal(312,315). Then the RS creates a pilot signal to be transmitted to the BS and adjusts the power of the created pilot signal using the power of the pilot signal contained in the received uplink signal(317). The RS transmits the created pilot signal to the BS(319). The BS measures the power of the pilot signal transmitted from the RS and estimates the channel of the RD link using the measured pilot signal power and the estimated SR link channel value(321).

    • An apparatus and a method for reducing pilot overhead in a wireless communication system are provided to increase the efficiency of data transmission by transmitting more data by reduced pilot overhead. A data symbol mapper(405) maps data symbols to be transmitted into subcarriers, and detects values of the data symbols mapped into selected subcarriers. A pilot generator determines masking codes for each pilot group by using the detected values of the data symbols, and masks the masking codes into pilot symbols of the corresponding pilot group. A pilot symbol mapper(409) maps the masked pilot symbols received from the pilot generator into subcarriers.
