本文利用宽带MIMO信道测量数据评估了真实住宅环境中MIMO-OFDM系统的吞吐量性能。除了 SISO-OFDM 系统的性能之外，还进行了计算机模拟，以比较 MIMO-OFDM 系统与各种检测方法（即 MMSE、VBLAST、QRM-MLD 和 SVD-MIMO）的性能。结果表明，在完美CSI反馈的假设下，SVD-MIMO传输可以提供最高的平均吞吐量和中断吞吐量。另一方面，QRM-MLD 在发射机处没有可用 CSI 的系统中产生了最佳性能。研究还发现，由于真实家庭环境中空间相关性的存在，MMSE和VBLAST的中断吞吐量性能严重下降
In this paper, throughput performance of MIMO-OFDM system in real residential home environment was evaluated by using wideband MIMO channel measurement data. Computer simulations were carried out to compare the performance of MIMO-OFDM systems with various detection methods, i.e. MMSE, VBLAST, QRM-MLD and SVD-MIMO, in addition to that of the SISO-OFDM system. The results showed that the SVD-MIMO transmission can provide the highest average and outage throughput under the assumption of perfect CSI feedback. On the other hand, QRM-MLD yielded the best performance among the systems without CSI available at the transmitter. It was also found that the outage throughput performance of MMSE and VBLAST degrades severely due to the existence of spatial correlation in the real home environment
