    摘要: A method and apparatus for controlling power in a decode-and-forward (DF) relay system is provided. The method of controlling power in a DF relay system includes: acquiring first channel information of a first link between a source node and a destination node, second channel information of a second link between the source node and a relay node, and third channel information of a third link between the relay node and the destination node, by using a pilot signal; determining a power level of the source node from the acquired first through third channel information; and feeding back the determined power level to the source node and the relay node.

    摘要: A transmitter, a receiver, and a method of supporting a space time block code (STBC) scheme in a single carrier (SC) system based on a unique word (UW) are provided. The transmitter supporting an STBC scheme in an SC system based on a UW includes: a space time (ST) encoder encoding a plurality of symbols, which has been received according to a predetermined pattern, using a space time encoding; a first UW adder generating a first transmission sequence by inserting a first UW after a first symbol, from the encoded plurality of symbols; and a second UW adder generating a second transmission sequence by inserting a second UW after a second symbol, from the encoded plurality of symbols.
