For high-speed packet access, Hybrid Automatic Repeat reQuest (HARQ) and Multi-Input Multi-Output (MIMO) multiplexing are indispensable techniques. Single-Carrier (SC) MIMO block transmission using frequency-domain signal detection such as the frequency-domain linear detection based on the Minimum Mean Square Error Criterion (MMSED) can improve the HARQ throughput performance over the frequency-selective fading channel. However, the performance improvement is limited due to not only an Inter-Antenna Interference (IAI) but also an InterSymbol Interference (ISI) resulting from a severe frequencyselective fading.
