Cooperative relaying is a promising technique that improves the end-to-end error performance in multihop vehicular networks. When cyclic delay diversity (CDD) is employed as transmit diversity at each hop, the control of the delay time introduced at each transmitting station improves the diversity gain. In this paper, a novel distributed delay time selection algorithm for cooperative multi-hop vehicular...
Cyclic delay diversity (CDD) is a simple transmit diversity technique for coded OFDM systems with multiple transmit antennas. It is applicable to existed wireless communication systems since it does not need modifications of the standard OFDM receiver. However, CDD causes serious degradation in the performance of post-FFT estimation, i.e., integer frequency offset (IFO). This paper suggests pilot...
