- Abstract
- In this paper, the cooperative coding using cyclic delay diversity (CDD) for multiuser OFDM systems is introduced. In proposed scheme, multiple terminals with a single antenna share their resources and exploit spatial diversity. Also, in order to increase frequency selectivity in the relay channel, different cyclic time delay is used at the relays. Analysis of frame error probability (FEP) for proposed cooperative coding using CDD is shown. Simulation results show the frame error rate (FER) for various consideration. The proposed scheme provides the diversity gain according to the number of relays and cyclic delay. © 2008 IEEE.
