摘要： An apparatus and a method for detecting signal using multivariate polynomial in multiple input multiple output communication system are provided to reduce the complexity of the calculation than non-linear detection method by performing signal detection using multivariate polynomial. A plurality of RF receivers(110-1 through 110-N) down-converts RF band signals received through each antenna to baseband signals. A plurality of RF receivers provides the training symbol and data signal received through a plurality of antennae to the signal detector(120). The signal detector detects transmission signals from each for each antenna received signals provided from a plurality of RF receivers. Particularly, the signal detector spreads the received signal vector out the multivariate polynomial. In that way the transmission signal vector is detected. A channel estimator(130) estimates channel with the transmitting end using a predetermined signal. An interference canceller(140) is detected from the signal detector, the stream much interference component is removed.

摘要： 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.

摘要： An apparatus and a method for selecting a path in a broadband wireless communication system are provided to select a path by using a transmission rate with respect to a base station-terminal link and a relay-terminal link and a queue state of a base station and a repeater. A base station selects one of modes for path selection(600). The base station receives a report on an SNR(Signal-to-Noise Ratio) value obtained by measuring a radio channel state between the base station and a terminal and between a relay station and the terminal from the terminal(602). If the base station needs to receive the SNR value between the base station and the relay station(604), it receives the same from the relay station(606). If the SNR between the base station and the relay station is not required, the base station calculates a data transmission rate between the base station and the terminal and between the relay station and the terminal by using the reported SNRs between the base station and the terminal and between the relay station and the terminal(610). The base station determines whether to transmit data through a direct path from the base station or by way of the relay station(612). The base station transmits information about the determined data transmission path to the relay station and the terminal(614).

摘要： An apparatus and a method for generating a synchronization channel for a RS in a wireless communication system are provided to generate a synchronization channel for the RS by using a sequence value of a synchronization channel and a sequence value of a common mask transmitted from a BS(Base Station) to each MS, thereby lowering complexity in generating the synchronization channel by enabling a downlink synchronization channel transmitted from the BS to the each MS to be separated from the synchronization channel for the RS. A method for generating a synchronization channel for a RS(Relay Station) in a wireless communication system using a multi-hop relay method comprises the following steps of: checking a sequence of a synchronization channel for an MS(Mobile Station) and a predetermined length of a preset sequence(a common mask)(701,703); and generating a sequence of a synchronization channel for the RS by performing XOR operation for the sequence of the synchronization channel for the MS and the predetermined length of the sequence(705).

摘要： 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).
