Abstract(in English) | DS/CDMA systems feature being extremely tolerant of interference and fading. However, they have a serious problem that there occur so-called co-channel interferences due to the correlation between the spreading codes of co-channels. So, the quality of communication might be degraded. To overcome this problem, various systems have been proposed, which suppress co-channel interferences by utilizing adaptive arrays. This paper proposes a new system, which applies the DCMP adaptive array to the OFDM-CDMA systems. In this system, an array response vector of the desire signal can be estimated by the ESPRIT algorithm with the adaptive spatial averaging in the frequency domain. Computer simulation results show that the proposed system can suppress the interferences even with effects of the Doppler shift and mutual coupling of the array. |
