摘要： A space-time code has a codeword matrix. The codeword matrix is a square matrix with dimension equal to the number of the transmit antennas, wherein a row of the codeword matrix represents combined signals transmitted by each transmit antenna and a column of the codeword matrix represents timeslots of the number of the transmit antennas. Signals are transmitted through the rows of the number of spatial multiplexing rate, in each column of the matrix. Further, the symbols of the number of the transmit antennas are combined by way of utilizing complex weights, in each row of the matrix. With this space-time code, a delay is minimized, so that change of channels can be managed efficiently. Also, the space-time code has minimum number of data symbols, and thus its complexity is minimized.

摘要： Disclosed is a method of using relay that may continuously transmit data without time division based on superposition coding in a communication system. When transmission of a relay-supported user signal via a base station-relay link is performed, the method of using relay based on the superposition coding reuses a resource allocated to a direct-transmission user based on the superposition coding to perform the transmission. According to example embodiments, a separate resource for the base station-relay link may not be needed, and continuous relay transmission is possible without time division, thereby substantially increasing frequency efficiency and reducing a transmission delay caused by the use of the relay.

摘要： A system and method for transmitting data by a base station in a multiple access communication system including a plurality of sub-channels, each of which includes a predetermined number of sub-carrier bands, the sub-carrier bands being divided from an entire frequency band. The method includes the steps of: dividing input data streams in a unit of the sub-channels corresponding to each terminal into a plurality of data sequences based on a predetermined length; spreading each of the data sequences by a distinct spread spectrum code, respectively; summing and parallel-converting the spread data; hopping each frequency of the parallel-converted data in the unit of the sub-channels based on a frequency hopping pattern allocated to each of the terminals in advance; performing an inverse fast Fourier transform with respect to the hopped parallel-converted data; and transmitting the transformed data.
