Study on transmit/receive antenna diversity for multi-carrier transmission

چکیده
Abstract 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 effect and improve the transmission performance. Transmit/receive antenna diversity is well-known for further improving the transmission performance. In this paper, we propose a new transmit/receive antenna diversity technique in which the equalization processing for transmission and reception can be implemented at the one transmit/receive side, and the BER performance is evaluated by the computer simulation.

Space-frequency Block Coded-joint Transmit/receive Diversity for Multi-carrier Transmission
Space-frequency block coded transmit diversity (SFBC) is under intensive study to improve the transmission performance of multi-carrier transmission in a frequencyselective fading channel. However, in the conventional SFBC, the transmission efficiency degrades when more than 3 transmit antennas are used. Recently, we proposed a spacetime block coded-joint transmit/receive antenna diversity (STB...
