Executive Summary

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, the authors 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, they 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 Space Time block coded Transmit Diversity (STTD).
