| Popis: | We propose 3-hop cooperative diversity using QOSTBC (Quasi-Orthogonal Space-Time Block Code) [1], which offers 3-hop cooperative diversity without signal separation in relay nodes. The key of our proposed scheme is encoding signal sequence in different signal unit according to relay stage. This letter explains details of the proposed scheme and shows that it offers interference reduction among streams and space diversity gain by result of simulations. |
