| Abstract: | Per-antenna rate control(PARC) is an efficient way to increase throughput of multi-stream multiple-input multiple-output(MIMO) systems.In time-varying channels,however,the channel quality indicator(CQI) fed back to the transmitter becomes is outdated.There is a mismatch between the selected transmission scheme and actual situation.Therefore,the system performance may be degraded.We propose an improved transceiver structure for PARC based multi-stream MIMO system considering the channel delay effects of CQI ... |
