Space-frequency Block Coded-joint Transmit/receive Diversity for Multi-carrier Transmission
نویسندگان
چکیده
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 (STBC-JTRD), which allows the use of an arbitrary number of transmit antennas while limiting the number of receive antennas to 4. In this paper, we propose a space-frequency block coded-joint transmit/receive diversity (SFBC-JTRD) for the multi-carrier transmission. Its achievable bit error rate (BER) performance is evaluated, by computer simulation, to compare with the conventional SFBC and STBC-JTRD. Keywords—Frequency-selective fading channel, spacefrequency coding, multi-carrier transmission

Transmit Multi-Block FDE for Space-Time Block Coded Joint Transmit/Receive Diversity in a Quasi-Static Fading Channel
In this paper, we propose a transmit multi-block frequency-domain equalization (MB-FDE) for frequency-domain spacetime block coded joint transmit/receive diversity (FD-STBC-JTRD). Noting that a STBC codeword consists of multiple coded blocks, the transmit MB-FDE uses the multiple transmit FDE weight matrices, each associated with each coded block. Both single-carrier (SC) transmission and ortho...

In this paper, joint transmit/receive frequency-domain equalization (FDE) is proposed for analog network coded (ANC) singlecarrier (SC) bi-directional multi-antenna relay.

Abstract Recently, frequency-domain pre-equalization (pre-FDE) transmission has been attracting attention for improving the SC transmission (e.g., DS-CDMA) performance in a frequency-selective fading channel. Antenna diversity reception is also a well-known technique for improving the transmission performance. However, so far the joint use of pre-FDE and the receive diversity has not been discu...
