摘要：
The cooperative transmission schemes based on the amplify and forward (AF) mode have the defect of low transmission rate and the exiting full-rate cooperative transmission schemes based on space-time code design have the defect of high detection complexity. Therefore, this paper makes the best of linear constellation precoding (LCP) technique and cyclic delay diversity (CDD) technique, and adopts the non-orthogonal amplify and forward (NAF) mode, finally proposes a new full-rate wireless cooperative transmission scheme based on space-time-frequency code design. Compared with the cooperative transmission schemes that only pursue the transmission rate or the BER performance, this new scheme can apply to multi-relay scenario, and has the advantages of simple structure, low signal detection complexity that does not increases with the number of relay nodes. All of above makes the real-time data transmission service of high quality come to be possible.
