| Abstract(in English) | High speed data transmissions are required for the next generation mobile communication systems. However, broadband mobile channel is composed of many propagation paths with different time delays, producing severe frequency-selective fading channel. Recently, multi-carrier code division multiple access (MC-CDMA) has been attracting much attention for the broadband wireless access in the next generation mobile communications systems. MC-CDMA can exploit the channel frequency-selectivity to achieve the frequency diversity gain and improve the transmission performance. Transmit/receive antenna diversity is a well-known technique for further improving the transmission performance in a fading channel. Recently, we proposed the space-time block coded-transmit/receive antenna diversity (STBC-TRD), in which the equalization processing for transmission and reception can be implemented at the one transmit/receive side. However, in the previously proposed STBC-TRD scheme, the number of receive antennas is limited to 2. In this paper, we propose a new transmit encoding for STBC-TRD, which can employ the 4-branch receive antenna diversity. The achievable BER performance is evaluated by computer simulation and is compared with that of joint space-time transmit diversity (STTD) and antenna receive diversity. |
