    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.

    摘要： A new diversity scheme for orthogonal frequency division multiplexing/multi-input multi-output (OFDM/MIMO) systems. The new diversity scheme, i.e., turbo layered space-frequency coded OFDM (TLSFC-OFDM), uses the turbo principle with space hopping (SH). The TLSFC-OFDM system uses a successive interference cancellation (SIC) algorithm to reduce the number of iterations. As a result, this scheme reduces computational complexity. Simulation results show that the SIC-based TLSFC-OFDM system outperforms a conventional OFDM/Horizontal Bell Labs Layered Space-Time (H-BLAST) system using a horizontal coding scheme.
