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

Abstract

Abstract-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 MC-CDMA HARQ using STBC-JTRD, and show that the STBC-JTRD provides a better throughput performance than the spacetime block coded transmit diversity (STTD).
