| Abstract(in English) | Recently, delay diversity techniques have regained attraction because of not only their simple structures but also superior performance. Delay diversity can be realized by transmitting delayed replicas of a signal from several antennas. A problem associated with delay diversity in combination with orthogonal frequency division multiplexing (OFDM) is that the delays may exceed the capability of an equalizer or require a longer guadrd interval, which may reduce bandwidth efficiency. An efficient solution against this problem is cyclic delay diversity, which transmits delayed replicas of an OFDM signal in a cyclic manner. In this paper, we propose a cyclic delay diversity technique with differential amplitude and phase shift keying (DAPSK) modulation. Numerical results show that proposed scheme can achieve full-diversity performance. Moreover, the optimum parameter of proposed scheme is also studied. |
