Throughput Performance of MC-CDMA HARQ using Space-Time Block Coded-Joint Transmit/Receive Diversity
Hiromichi Tomeba, Fumiyuki Adachi · 2009
Hybrid automatic repeat request (HARQ) is an indispensable error control technique for wireless packet access. A combination of multi-carrier code division multiple access (MC-CDMA) and HARQ can provide a good throughput performance in a severe frequency-selective fading channel. Recently, we proposed the space-time block coded-joint transmit/receive diversity (STBC-JTRD), which allows an arbitrary number of transmit antennas while limiting the number of receive antennas to 6. In this paper, we evaluate, by computer simulation, the throughput performance of MCCDMA HARQ using STBC-JTRD, and show that the STBCJTRD provides a better throughput performance than the spacetime block coded transmit diversity (STTD).
