Space-Time Block Coded Joint Transmit/Receive Diversity in a Frequency-Nonselective Rayleigh Fading Channel

Abstract

Antenna diversity is an effective technique for improving the transmission performance in a multi-path fading channel. Recently, transmit diversity has been attracting much attention since it can alleviate the complexity problem of the mobile terminals. Joint transmit diversity/receive diversity achieves a much improved transmission performance. In this paper, we propose a new space-time block coding algorithm for joint transmit/receive diversity, which requires the channel state information (CSI) only at the transmitter side. Unlike the conventional spacetime transmit diversity (STTD), the space-time block coded joint transmit/receive diversity (STBC-JTRD) can use arbitrary number of transmit antennas, while the number of receive antennas is limited to 4. STBC-JTRD achieves a larger diversity gain than joint STTD/receive antenna diversity. The bit error rate (BER) analysis in a frequency-nonselective Rayleigh fading channel is presented. The BER performance is evaluated and is confirmed by the computer simulation. key words: antenna diversity, space-time block coding, time-division duplex

Channel capacity of distributed antenna network using spacetime block coded-joint transmit/receive diversity

“…A combination of J and Q is shown in Table 1 for N r =1~4. As shown in [7,8], FD-STBC-JTRD achieves an N t ×N r -order maximal ratio combining (MRC) diversity. The FD-STBC-JTRD encoding requires the CSI between each transmit/receive antenna pair.…”

Throughput Performance of MC-CDMA HARQ using Space-Time Block Coded-Joint Transmit/Receive Diversity

“…While the throughput performance can be improved as N r increases from 1 to 2, the performance improvement is smaller than by increasing N t . This is because that the received signal-to-noise power ratio (SNR) after the STBC-JTRD decoding is reduced by a factor of 1/N r [14]. It should be noted that the throughput when more than 2 receive antennas are used is smaller than when 2 receive antennas are used since the coding rate R of STBC-JTRD becomes less than 3/4 when more than 2 receive antennas are used.…”

“…Transmit antenna diversity has been attracting much attention because the complexity problem of a mobile terminal can be alleviated [9][10][11][12]. Recently, we proposed the space-time block codedjoint transmit/receive antenna diversity (STBC-JTRD) for a frequency-nonselective fading channel [13,14], which allows an arbitrary number of transmit antennas without sacrificing the coding rate while the coding rate of well-known spacetime block coded transmit diversity (STTD) is reduced when more than 2 transmit antennas are used [10]. We also showed [15,16] that the STBC-JTRD can be extended to the case of frequency-selective fading channel by introducing the frequency-domain pre-equalization (pre-FDE) [17,18].…”

Frequency-Domain Equalization for Block CDMA Transmission

“…Space-time block coded joint transmit/receive diversity (STBC-JTRD) was proposed 6 that can use an arbitrary number of transmit antennas while limiting the maximum number of receive antennas to 4. Frequency-domain pre-equalization 7 can be introduced to STBC-JTRD for both CDMA 8 .…”
