Patent ID: 8223887

Claim:
A receiver supporting a space time block code (STBC) scheme in a single carrier (SC) system based on a unique word (UW), the receiver comprising: a receiving antenna that receives a receiving sequence, the receiving sequence comprising a plurality of symbols and a UW; a fast Fourier transform module which performs a fast Fourier transformation of the receiving sequence; an interference component process module which eliminates an inter symbol interference component introduced by the UW and a second symbol of the plurality of symbols in the receiving sequence from the receiving sequence based on the UW to generate an interference-eliminated receiving sequence; an STBC combination module which combines the interference-eliminated second symbol and a first symbol of the plurality of symbols to generate a linear combined symbol; and a frequency domain-decision feedback equalization (FD-DFE) module which generates a present recovery symbol using a previous recovery symbol and the UW, from the linear combined symbol.
