Transmitter, receiver for supporting space time block code scheme in single carrier system based on unique word and method thereof

The present invention relates to a transmitter, a receiver supporting (Space Time Block Code) STBC scheme, UW (Unique Word) transmitting a signal according to the base transmission sequence and restore the orthogonality (Orthogonality) of the received sequence, in accordance with the received signal discloses a transmitter, a receiver and a method for supporting the STBC scheme, in the UW-based SC system by using UW, to obtain diversity gain and equalization gain at the same time and to achieve improved performance with no error propagation (error propagation) to do. In the UW based SC system according to the present invention, the transmitter supporting the STBC scheme is (Space Time) ST for encoding by using the space-time encoding a plurality of symbols inputted by the predetermined pattern the encoder, the one of the encoded plurality of symbols first UW adder, and a second transmission sequence by inserting a second UW in the transmission sequence of the second symbol of the plurality of symbols of the encoded for generating a first transmission sequence by inserting the first UW in the transmission sequence of the first symbol claim 2 is characterized in that it comprises an adder for generating a UW. UW (Unique Word), SC (Single Carrier), STBC (Space Time Block Code), FD-DFE (Frequency Domain-Decision Feedback Equalization)
