Performance Comparison Between MIMO and SISO based on Indoor Field Measurements

Shailesh Chaudhari, Jingy Hu, Babak Daneshrad, Jesse Chen

摘要:

在本文中,我们量化的性能增益实现,如果SISO系统取代4x 4 MIMO在WLAN设置兼容IEEE 802.11n标准。我们比较吞吐量和功率节省在MIMO在不同的室内位置进行现场测量。测量验证与模拟,包括不同的IEEE TGn信道模型。对于MIMO和SISO之间的比较,我们选择了调制和编码方案(MCS),它产生最高的吞吐量受到QoS约束(PER <10%)。我们表明,2.5倍-3倍的吞吐量增益和5-15 dB的功率节省是在4 × 4 MIMO系统中实现的。

英文摘要:

In this paper, we quantify performance gain achieved if SISO system is replaced with 4x4 MIMO in WLAN setting compatible with IEEE 802.11n standard. We compare throughput and power savings in MIMO by taking field measurements at various indoor locations. Measurements are validated with simulations that include different IEEE TGn channel models. For comparison between MIMO and SISO, we select the Modulation and Coding Scheme (MCS) which yields the highest throughput subject to QoS constraints (PER <10%). We show that throughput gain of 2.5x-3x and power saving of 5-15 dB are achievable in 4x4 MIMO system.
